CDS 7550S Pro
Product Introduction
Product Features
Dual Mode Focusing Trap
To improve the resolution of early eluting molecules, CDS adopts pre-desorb and pre-heat technique along with Peltier cooling to mechanically and chemically confine analytes on the analytical trap to improve focusing
Automated IS Addition
Automatically and reproducible add internal standard from a 5mL loop up to 10 times
Pre-Trap Sample Split
Reproducibly split up to 99% of sample using a dual-channel mass flow controller to prevent overloading of the focusing trap
Automated Sample Saver
Chose to recollect a fraction of sample on the original TD tube for high priority customer samples, replicates, or method validation
Pre-Loaded Method Library
Select from a pre-loaded method library to support a variety of applications such regulatory, dirty samples, tube conditioning, troubleshooting, and more
Leak Checking for Hydrogen
Select hydrogen as a GC carrier gas for expanded leak check for each sample as an added safety precaution when using hydrogen
