EST Analytical AS120 GC & GC/MS AUTOSAMPLER

Importance of GC Autosampling in Analytical Chemistry

Automated sample introduction for gas chromatography (GC) and GC–mass spectrometry (MS) is essential to ensure consistent injection volumes, reduce manual errors, and achieve high laboratory throughput. The AS120 autosampler addresses these needs by offering a robust and economical solution.

Objectives and Overview

The AS120 aims to provide reliable and flexible sample handling for a wide range of GC and GC–MS applications across industries such as pharmaceuticals, environmental testing, food and flavors, and petrochemicals. It combines direct syringe injection, dual inlet capability, and customizable tray configurations to meet diverse analytical requirements.

Used Instrumentation

The AS120 GC & GC/MS autosampler includes:

• Direct syringe injection with variable fill and injection rates
• Dual inlet support for split and splitless operation
• Air gapping to minimize cross-contamination
• Compatibility with any GC or GC–MS system

Available syringe volumes range from 1.5 to 100 µL. The system accommodates multiple solvent and waste bottles and supports method linking for complex sequences.

Main Methodology

Sample introduction is performed via automated syringes that draw precise aliquots, incorporate programmable air gaps, and deliver consistent injections. The autosampler supports a variety of vial sizes and capacities, from 28 × 40 mL to 120 × 2 mL vials, enabling both high-throughput and specialized workflows.

Main Capabilities and Performance Discussion
