A demo of AMDIS for processing EI GC-MS files is presented. In addition to the NIST Search software the components can be identified within AMDIS using either commercial or user libraries.

A demo of NIST MS exact and similar structure search for finding model compounds is presented. A user can use their preferred drawing programs for inputting structures into the NIST MS Search program.

A demo of NIST MS search for identifying components in EI GC-MS analyses is presented. The data is acquired on a variety of GC-MS systems then sent to the NIST MS search for processing.

In brewing analytics the most frequently used gas chromatographic detectors are (FID), (ECD), and (FPD). This work is focused on principles, their advantages and limitations during using in brewing analytics.

This paper addresses some specifics concerning the use of hydrogen as carrier gas in different techniques of sample introduction on chromatographic column.

This article is focused on the chromatographic parameters such as retention time and selectivity after switching to the use of hydrogen or nitrogen.

Some difficulties with substitution of helium as carrier gas by another gas are discussed in this series of papers. Laboratories may be forced to make this change due to “helium crisis”.
