Automatic solid-liquid integration National standard purge and capture Instrument- Reliable manufacturers in Beijing Brief introduction of PTC - Ⅲ instrument

Ptc-iii solid / liquid purge and trap is a 70 bit solid-liquid integrated automatic purge and trap with electronic cold trap. The sample can be directly swept and collected in the distillation bottle, and the sample can also be automatically swept and collected by mixing the sample with water.

Combined with GC or GC / MS, it can be widely used in environmental analysis, such as the analysis of organic pollutants in drinking water, waste water, soil, and volatile compounds (such as odor components) in food. The instrument meets the standards of "hj639-2012 determination of volatile organic compounds in water quality / gas chromatography-mass spectrometry", "hj686-2014 determination of volatile organic compounds in water quality by Purge and trap / gas chromatography-mass spectrometry", "hj605-2011 determination of volatile organic compounds in soil and sediment by Purge and trap / gas chromatography-mass spectrometry" and other standards.


Full automatic solid-liquid integrated purge and trap instrument - Beijing steadfast PTC - III main features:

  • GC-MS and GC-MS can be used;

  • Simple operation, easy to use, software control, high degree of automation: just put the sample tube into the sample tray, all operation and control are completed by the control software, so the sample repeatability is good; the design of large touch LCD board in the host can track the temperature and operation command in the whole process.

  • The lowest refrigeration temperature is - 30 ℃ (room temperature is 20 ℃), which can meet most of the requirements of low temperature enrichment.

  • The trap was heated by direct resistance, and the heating rate was more than 2400 ℃ / min.

  • The built-in foam sensor can detect the foam in the purge tube to prevent contamination of the sample path and protect the entire analysis system.

  • The user can define the cleaning times of sampling probe and purging tube.

  • The solid sample bottle can be heated, and distilled water can be injected directly to mix and purge.

  • The trap is separated from the purge tube to reduce cross contamination between samples. During the blowback cycle, compounds blown out of the trap will not flow into the purge tube.

  • The effect of water vapor on GC and GC / MS is greatly reduced.

  • PEEK material and silylation inert treatment of stainless steel pipe were used in the sample pipeline to reduce the residual pollution.

  • Hot water can be used to flush pipes and purge pipes to reduce residues.

  • All pipelines and six way valves can be heated at controlled temperature to eliminate the cold point of the system and reduce sample loss.

  • Synchronous interface is provided to start chromatography and workstation at the same time of injection
