AS 5250 Pyrolysis Autosampler

Increase the throughput of your pyrolysis laboratory by using the AS5250 Pyroprobe® Autosampler. The AS5250 provides hands-free analysis of up to 36 samples and enhances operational capacity allowing unattended operation over a weekend or holiday period. Solid, viscous liquid and powder samples are analyzed directly, eliminating the need to perform lengthy sample extractions or derivatizations. A patented heating method provides the flexibility to perform both high performance thermal desorption and pyrolysis on the same sample. Microsoft Windows® compatible software facilitates methods development and allows for standard operating procedures to be written for GLP/GMP compliance.*

As most seasoned chromatographers know, CDS Analytical is the world's premier pyrolysis manufacturer. What you may not know is that CDS also has produced purge & trap instruments for over 25 years-originally under the Peak Master name, and then under an exclusive private label contract with a major US supplier.

CDS has expanded the instrument with an optional internal electronic flow control option. Without changing the flow path or electronics, we have added electronic flow control so that the operator can individually control purge and GC flows during the purge cycle, trap dry, trap desorb and trap bake. This will allow increased throughput for each sample batch, allowing you to run more samples per instrument.
