The HP 7694 Headspace Sampler utilizes a dynamic headspace technique, which allows for the efficient and accurate extraction of VOCs from a sample. This technique involves heating the sample in a sealed vessel, which drives the VOCs into the headspace above the sample. The headspace gas is then transferred to the analytical instrument for further analysis.
The instrument's high-precision temperature control system ensures that the sample is heated to the desired temperature with precision, ensuring that the extraction of VOCs is consistent and reproducible. The HP 7694 Headspace Sampler also features a high-capacity vial holder, which can accommodate up to 12 vials at a time, reducing the time and effort required for sample analysis.
The HP 7694 Headspace Sampler is equipped with a range of safety features, including a pressure relief valve and a fused quartz injection system, which helps to prevent sample carryover and ensures that the injection system remains clean and free of contamination. The instrument also features a built-in vacuum pump, which allows for the efficient removal of air from the sample vial, reducing the risk of contamination and ensuring that the VOCs are accurately represented in the headspace.
In summary, the Hewlett-Packard 7694 Headspace Sampler is a high-performance, advanced analytical instrument that is designed for the quantitative analysis of volatile organic compounds (VOCs) in various matrices. Its innovative design, robust construction, and user-friendly interface make it an essential tool for laboratories in various industries. Its dynamic headspace technique, high-precision temperature control system, and safety features ensure accurate and reliable results, reducing the time and effort required for sample analysis.
