PT 7000, The best Purge and Trap Instrument
Are you looking to efficiently remove volatile organic compounds from water samples for analysis? Look no further than the PT 700 Purge and Trap Instrument. This innovative technology purges VOCs from water samples using an inert gas, then transfers them to a headspace phase for concentration in a trap tube. Let's dive into the details of how this process works and why it's the best option for your analytical needs.
How does the PT 700 Purge and Trap Instrument work?
The PT 700 works by purging water samples with an inert gas, such as helium or nitrogen, to force the volatile organic compounds into a headspace vapor phase. This phase is then captured and concentrated in a trap tube. The components are desorbed by rapidly heating the trap tube, allowing them to be introduced into an analysis column for further testing.
What are the advantages of using the Purge and Trap method?
Unlike static headspace sampling and SPME methods, the Purge and Trap method minimizes the risk of data dispersion due to matrix effects. This means that the concentration of salt in the sample does not alter the gas-liquid equilibrium, eliminating the need for a salting out operation. As a result, components can be efficiently recovered without the risk of interference from the sample matrix.
Why choose the PT 700 Purge and Trap Instrument?
The PT 700 offers significant operational advantages over other sampling methods. By efficiently purging VOCs into a headspace vapor phase, this instrument ensures accurate and reliable results without the need for additional sample preparation steps. The precise control and automation features of the PT 700 make it the ideal choice for laboratories seeking high-throughput and reproducible analyses.
When it comes to analyzing water samples for volatile organic compounds, the PT 700 Purge and Trap Instrument stands out as the top choice for researchers and analysts. Its innovative design and efficient purging capabilities make it a valuable tool for any laboratory looking to achieve reliable and accurate results in VOC analysis.
