Main specifications

1. Dilution Ratio: ppb-ppt level;

2. Pressure Measurement: 0-50 psi (Accuracy ≤ ±0.05%);

3. Operation Modes:

Std Prep / Standard Preparation Mode

Flush / Purge Mode

Pressurize / Pressurization Mode

Spike / Internal Standard Mode

Main functions

1. Compatible with multiple sampling modes including canister sampling, online sampling, and sorbent tube sampling. The system can be coupled with Gas Chromatography (GC) or GC-Mass Spectrometry (GC-MS) for high-sensitivity detection at ppb to ppt levels;

2. Features three-stage cryogenic trapping technology with intelligent water removal design and precise temperature control for efficient sample enrichment. Complies with international standard methods including EPA TO-14A, TO-15 and TO-17;

3. Fully inert flow path design (SilcoNert® stainless steel and fused silica materials) combined with wide-range temperature control capability (-150°C to 300°C) ensures sample integrity and prevents cross-contamination
