Summary:
The CDS Pyroprobe 6400 is an advanced pyrolysis GC/MS system designed for microplastics analysis, polymer characterization, additives analysis, and materials research applications. Built on CDS’s 6th generation Pyroprobe platform, the 6400 features DISC (Drop-In Sample Chamber) technology for rapid sample loading and introduces a new large sample tubes that hold more than 3x times the sample compared to our 6150 and 6200.
The system connects directly to virtually any GC/MS platform through a heated transfer line, allowing flexible installation without permanent instrument modification. The Pyroprobe 6400 supports fast and reliable Py-GC/MS analysis for universities, environmental laboratories, forensic applications aindustrial materials testing.
Product Features

New Enlarged Disc Design
The new 6400 Pyroprobe new, enlarged Drop In Sample Chamber (DISC) sample loading system. This system makes the loading of pyrolysis tubes a quick and trouble-free operation.

Easier Sample Loading
With the new enlarged sample tube, load more sample or entire quartz fiber filters for easier sample preparation.

High Temperature Valve Oven System
CDS's valve oven design guarantees the sample path is evenly heated without cold spots. A heating temperature of 350°C assures minimal carry over.
