Operation

TurboMatrix 350 ATD: Automated sampling of up to 50 tubes,

incorporating PPC. Supports pressure, flow and velocity control of

the carrier gas through the GC column. Overlaps tube desorption

with GC analysis for optimum productivity. Also incorporates

loading of internal standard into clean tubes to provide sample-

integrity validation and to improve precision (repeatability) of the

analysis. Allows the ability to condition tubes during

chromatography to minimize downtime and enhance productivity

and also includes a separate trap-clean-and-test function which saves

time and protects the GC column and detector.

TurboMatrix 650 ATD: Automated sampling of up to 50 tubes,

incorporating all of the performance features of the TurboMatrix 350

ATD model plus the ability to re-collect sample (on the source or a

new tube) for repeat analysis, the ability to perform dry purge of the

tube without the internal standard accessory, and the ability to

perform tube and trap impedance measurement as a diagnostic of

adsorbent bed condition.

All models of the instrument can have one or the other of the

following accessories. Generally these options are installed at the

factory but can be installed as a field upgrade. Contact the

PerkinElmer service department for further information.

Internal Standard: Allows loading of internal standard into clean

tubes to provide sample integrity validation and to improve precision

(repeatability) of the analysis.

Continuous Online Monitoring: “On-line” is a continuous

sampling mode in which sample is drawn through the ATD/TD and

sampled at regular intervals. During continuous monitoring, the

sample is drawn in through an empty sample tube and onto the cold

trap.
