Frequently Asked Questions
Q
What sample bottle sizes are compatible with this system?
The system supports sample bottles of 40ml and 60ml, with a minimum sample injection volume of 25ml using the in situ headspace blowing method.
Q
How many samples can be captured simultaneously?
The three-channel capture and desorption module allows simultaneous capture of three or more samples, significantly improving testing efficiency.
Q
How is a stable baseline ensured during testing?
The external gas phase provides a dedicated analytical gas supply, which ensures stable testing conditions and maintains a consistent, reliable baseline throughout the analysis.
Q
How does the system prevent cross-contamination between samples?
The system employs a dry cleaning process with argon gas back-blowing of the trap at high temperature, effectively eliminating residual compounds and preventing cross-contamination between successive samples.
Q
What measures are taken to protect the Tenax tube and chromatographic column?
A pipeline liquid inlet detection mechanism is integrated into the system to monitor and prevent water vapor from entering the Tenax tube and the chromatographic column, protecting the integrity of both components.
Q
What are the advantages of the high-power thermal desorption heating system?
The high-power heating system features an insulation design that ensures uniform thermal desorption temperature across the entire sample, resulting in more consistent and reproducible analytical results.
