Entech's 7500 Series Robotic Autosampler

Take advantage of today's Fast GC systems, quadruple your throughput and extend the compound recovery range. The 7500 Robotic Autosampler allows unattended analysis of up to 60 samples.

Interchangeable sample trays are available for 60 of our MC200 canisters or VOA vials, 28 of our MC450 and MC600 canisters or 16 oz vacuum extraction vials and 13 of our MC1400 canisters or 1L vials.

The single sample line is coated with Silonite®, a flexible layer of fused silica which maximizes recovery of polar and thermally labile volatile chemicals, even in dry or artificial matrices. The single inlets allow switching from high to low concentration samples without the carryover problems of valved, multi-inlet systems.

The 7500 performs a unique constant flush which eliminates any carryover from the previous sample.

The 7500 Robotic Autosampler's

modular design accommodates

four canister sizes ranging in

volume from 200 cc - 1.4 L

and six vials sizes ranging

from 40ml-1000ml

The heated robotic sampling head moves samples to the heater and applies pulsed vacuum directly through a heated transfer line for maximum transfer efficiency

Applications

• Packaging Analysis

• Material Testing

• Chemical Warfare Agent Testing

• Process Gas Testing

• CO2 Analysis

• Industrial Hygiene

• Indoor Air / Environmental Testing

• Product Testing (VOC Emissions

Sample Heating

Heated or unheated analysis is your choice with the 7500 Autosamplers. Samples are automatically transferred to the oven to await analysis. Multiple heated zones condition samples, saving you time and allowing for optimal heating. Heating can commence on the next one or two samples while the current sample is being analyzed.

Sample Volume Range

7500 Autosamplers are compatible with GC loop injection for 0.1 - 2 cc samples. The Entech 8000 inlet, in conjunction with the cryo-focusing option, is the ideal solution for 2 - 30 cc injections. This combination makes it possible to recover compounds that range from C3 - C25.

A 7500 Autosampler in conjunction with the Entech 7100A Preconcentrator is suitable for the analysis of C2 to C18 compounds, concentrating 10 to 1000 cc's. The volume from multiple sample positions can also be combined for even lower detection limits.

Features

Interchangeable sample trays optimize applications for canisters and LVSH/LVDH.  Reducing bushings further increase the flexibility of the 7500
