An all-in-one autosampler, similar to the CTC PAL and TriPlus autosamplers. The flagship model Flex2 supports liquid, headspace and SPME samples.

Key features of the EST Flex 2 Autosampler:

• User friendly drag-and-drop functionality
• No expensive software upgrades to
purchase
• Maximize GC productivity through
overlapping prep routines
• Simplified menu options that can be
easily edited with no need for macro
programming
• Unsurpassed agility with line-by-line
editing capability without sequence
interruption
• Real-time run-status screen enables up
to the minute analyst confidence
• Automated calibration of tray and accessories minimizes traditional set-up time
• .CSV Sequence integration with
Chemstation and OpenLAB

EST AS120

The AS120 Autosampler is an affordable all-electric, stepper motor driven XYZ GC Autosampler that combines state-of-the-art component technology with easy-to-use operating features that meet routine as well as research level auto sampling requirements for GC GC/MS analysis.

Maximum Productivity

Dual Injector Operation allows maximum productivity from GC with dual injectors and columns.
Programmable Injector Alignment: No manual adjustments to align injection ports.
Variable Injection Rate to optimize chromatography based on injector type and analyses of interest.
Large 120 or 200 position sample tray for overnight operation that lifts off for easy loading.

EST Purge & Trap

Liquid Gas Extractor

Water Analysis using GC Made Easy

Why choose purge & trap? How does it compare to other sampling techniques?

With purge and trap analytes are purged using an inert gas from their matrix onto a thermal desorption trap which is then heated onto a GC.

With thermal desorption, you feed samples directly onto the trap and then desorb them into a second trap within your system, which is arranged much like the purge and trap.

Dynamic headspace, on the other hand, does not use a trap, as samples are heated in a closed vial and the volatilised gases are forced onto a GC.

In summary, purge and trap is best used for water matrices, thermal desorption best for air and dynamic headspace best for solids.

The Purge and Trap technique is more sensitive by at least a factor of 1000 over headspace techniques. Typical sensitivity is in the ppb range. By purging samples at higher temperatures, higher molecular weight compounds can be detected.

Great For Analysing Methane in Water

Dissolved gas, called RSK or Shale Gas, and headspace analysis is becoming more prevalent in today’s environmental lab. There is a constant need to analyse the dissolved gas content of aqueous solutions. This increase is driving the need to automate this testing. EST analytical now provides a solution that automates this testing, making your laboratory more productive and reliable. Now your lab can stay EPA 5035 and (ASTM) Method D8028 compliant when running RSK-175. RSK is a time consuming, labour intensive analysis that requires manual preparation of sample vials prior to the headspace analysis.

The LGX-50 liquid gas extractor completely automates the sample prep for headspace analysis of Methane, Ethane, Ethene, and other compounds in water.
