<h3>The recommended procedure for H53 method integration in Clarity (method 1):</h3>
<ol>
<li>Use Baseline – Lock on the whole chromatogram.
</li>
<li>Apply Baseline – Allow Crossing to the whole chromatogram with the option To Start/End.
</li>
<li>Via Peak – Add positive, add the following peaks:
</li>
</ol>
<ul>
<li>A peak with the start time just before the solvent peak (this is the initial point of the baseline) and the end time at the beginning of the first fraction.</li>
<li>The first fraction (C10) peak with the start time exactly at the end time of the previous peak and the end time at the end of the fraction.</li>
<li>In a similar manner, i.e., with non-overlapping time frames, add the other peaks for remaining fractions (optionally, C10–C20, C20–C30, and C30–C40).</li>
</ul>
<ol start="4">
<li>Set Baseline – Together and Baseline – Forward horizontal over the entire chromatogram.
</li>
<li>Assign peaks to respective fractions using Force Peak Name (exact times are filled automatically when selecting the peak from the graph).
</li>
<li>Create a calibration file for the present fractions.
</li>
</ol>
When the chromatogram is integrated appropriately, you can use the Method - Save as Template command from the Chromatogram window to save the method as a template method, so it can be used for further measurements. In the case you have already measured all the samples, you can apply the integration on all your chromatograms via Analysis – Batch reprocess by method.

Note: In the case, that the amounts of some compounds in standards are not known, it is necessary to set the Curve Fit Type to Free Calibration on the tabs of these compounds in the Calibration window.

<h3>An alternative procedure for H53 method integration in Clarity (method 2):</h3>
<ol>
<li>Use the same Peak Width and Threshold as in standard integration.
</li>
<li>Apply Baseline – Together to the whole chromatogram.
</li>
<li>Apply Baseline – Forward Horizontal to the whole chromatogram.
</li>
<li>Mark all the peaks between C10 and C40 as a group (the group boundary lines may exceed the C10 and C40 peaks, only fully contained peaks will be included).
</li>
<li>Amend the peak starts and ends by manual peak tools if necessary for the C10 and C40 (use the Peak - Both, with the A time corresponding to the respective C10 or C40 time and B time positive or negative, respectively. The times are relative, i.e., will be shifted accordingly in other chromatograms).
</li>
<li>Create calibration file for C10, C40, and Group A peaks.
</li>
</ol>
If the integration is not correct at this point (e.g., the integrated area for Group A between C10 and C40 peaks does not start/end exactly where the C10/C40 peaks end/start respectively, as shown in the figure below), an additional step might be added after step 3.: Apply again Baseline – Together to the whole chromatogram. Continue with the remaining steps.
To subtract a baseline, in the Method Setup – Advanced dialog, set the baseline chromatogram, and in the Matching, set No Change. The baseline file should be acquired on the stabilized system and preferably without injection of solvent or at least with a lower volume of the solvent. Otherwise, negative artifacts will appear, interfering with the correct baseline setting in Clarity later on.

<blockquote>
There is a condition that must be met:
</blockquote>
<blockquote>
<ul>
<li>The drawn baseline must not cross the chromatogram line (the negative areas arising do not have any physical meaning).</li>
</ul>
</blockquote>
This approach is generally less reliable and more sensitive to the choice of Integration Algorithm.

Clarity software - NGA (Natural Gas Analysis) Extension

For analytical scientists working with chromatography and mass spectrometry, protecting sensitive information is crucial. Advances in instrument and software technology, combined with increased demands for in-depth analytics, has significantly increased the volume of valuable data that must be safeguarded from unauthorized access and potential breaches. One effective strategy to enhance security is to centralize data management, storing data away from the initial point of acquisition. Let us explore how this approach can significantly strengthen security for chromatography and mass spectrometry users and facilitate adherence to regulatory compliance measures surrounding electronic records.&nbsp;<h4>Understanding the analytical science landscape&nbsp;</h4>Chromatography and mass spectrometry are critical techniques in many fields including pharmaceuticals, environmental analysis and biochemistry. The data generated from these methods includes intricate details about potentially proprietary chemical compositions and biological information. Protecting this data is crucial to maintaining the integrity of scientific research and the competitive edge of organizations.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_Enhanced_Security_Through_Centralized_Data_Management_A_guide_for_Chromatography_and_Mass_Spectrometry_Users_95f6d464f1.webp" alt="Thermo Fisher Scientific: Enhanced Security Through Centralized Data Management - A guide for Chromatography and Mass Spectrometry Users" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_Enhanced_Security_Through_Centralized_Data_Management_A_guide_for_Chromatography_and_Mass_Spectrometry_Users_95f6d464f1.webp 245w," sizes="100vw" width="1200" height="600"><h4>The data security challenge&nbsp;</h4>Data acquisition, processing, storage and reporting has traditionally been conducted on isolated, static hardware-bound workstations. This approach presents significant security risks:<ul><li>Single point of failure: An isolated system with poor backup strategies can be vulnerable to catastrophic data loss via accidental damage or environmental changes. Any compromise can lead to data corruption, loss or unauthorized alterations.&nbsp;</li><li>Accessibility and convenience: Storing and processing data in a noisy lab environment can be inconvenient and impractical. Technical staff are often competing for access to instruments using the same workstation that others need for processing. This often leads to users manually transferring data outside of a controlled system for processing elsewhere. &nbsp;</li></ul><h4>The case for centralized data management&nbsp;</h4>Centralizing data management involves storing data in a central server location, away from the initial point of data acquisition. Here is how this approach can enhance security and usability for chromatography and mass spectrometry users:<ul><li>Reduced risk: A centralized system that has redundancies and backups in place can alleviate the risks associated with a single point of failure. Attackers trying to gain access will also have to deal with robust security measures not typically seen with isolated workstations&nbsp;</li><li>Enhanced data integrity: With separate systems for acquisition and storage, the integrity of the data is better preserved. Any unauthorized changes on the acquisition workstation will not directly affect the stored data.&nbsp;</li><li>Remote access and flexibility: Centralized data storage allows users to securely and conveniently access data from anywhere without manual transfer or copying the data.&nbsp;</li></ul><h4>Data retention, integrity and auditing&nbsp;</h4>Compliance with regulatory bodies such as the FDA (Food and Drug Administration) and &nbsp;EMA (European Medicines Agency) involves meeting stringent requirements for data integrity, security and retention. Centralized data management can help meet these requirements.<ul><li>Data integrity and audit trails: Separating acquisition from storage lets organizations ensure long-term raw data integrity and traceability by controlling access and providing audit trails.&nbsp;</li><li>Secure data retention: Regulations often mandate that data submissions be stored securely for extended periods. Dedicated data storage solutions can be designed to meet these requirements of large data volumes in a cost-effective way, while also protecting data from unauthorized access, accidental damage and environmental threats. &nbsp;</li></ul><h4>Practical implementation considerations for data security&nbsp;</h4>Chromatography and mass spectrometry users looking to deploy a centralized data management system should consider some data security essentials:<ul><li>Secure data transfer protocols: Use of encrypted channels for transferring data from the acquisition point to the central storage system.&nbsp;</li><li>Robust authentication mechanisms: Multi-factor authentication (MFA) to control access to both acquisition and storage systems. Single sign-on (SSO) systems also offer convenience.&nbsp;</li><li>Accessible audit trails and monitoring: Conducting regular security audits and continuous monitoring to detect and respond to potential threats promptly.&nbsp;</li><li>Leverage cloud solutions: Consider using cloud-based solutions that offer built-in security features for both data acquisition and storage. Many cloud providers offer specialized services that can help segregate these functions securely.&nbsp;</li><li>Compliance-focused data management: Ensure that the data management strategy aligns with regulatory requirements for data integrity, security and retention. This includes maintaining detailed records of data acquisition, storage, and processing activities.&nbsp;</li></ul><h4>Conclusion&nbsp;</h4>Centralizing data management by storing data away from the initial point of acquisition is a powerful strategy to enhance data security and facilitate regulatory compliance. Centralized data can be securely managed and shared remotely, allowing users to access data independently from the lab-bound workstations used for acquisition. Adopting secure data transfer protocols and robust authentication mechanisms can be made easier with modern cloud solutions. Scientists should feel empowered by these tools to protect their valuable data and maintain the integrity of their research. &nbsp;
