Product details
  • It can be used as an air monitoring technology (indoor, outdoor, workshop, car, breathing, etc.), as well as an effective tool for analyzing soil, polymers, packaging materials, food, seasonings, cosmetics, tobacco, building materials, drugs, and consumer goods. In fact, almost any sample containing volatile organic compounds can be analyzed using this technique.

    Accessory replacement: The injection pad, liner, polarizing electrode, collection electrode, and nozzle can all be replaced with one hand
    Main body replacement: The packed column, capillary sampler, TCD, and FID detector can be completely disassembled with just one wrench, making maintenance very convenient
    Nozzle: Unique high-temperature resistant quartz design, not easily broken and more inert, rotating seal, more thorough sealing
    Positioning: Unique capillary positioning system effectively ensures the repeatability of column installation and constant combustion rate
    Column head injection: Fill the column head injection to effectively prevent diversion discrimination effects

  • The blow sweep capture sample concentrator is used to process samples that require volatile organic compound (VOC) analysis by gas chromatography (GC) or gas chromatography/mass spectrometry (GC/MS) Can remove a large amount of water during the thermal desorption stage Efficient water removal enables the analysis of polar substances, such as alcohols, ethers, and ketones, without interference from water Reduce the performance of the chromatographic column and minimize the maintenance of GC or GC/MS

  • Standard 80 bit automatic sampling system

    ■ It can blow and capture various types of solid and liquid samples such as drinking water, wastewater, soil, and sludge

    Fully enclosed sample processing technology ensures no loss of samples during the preparation stage

    ■ Use a mass flow controller for programmatic flow and pressure control

    The only system that can simultaneously perform fully automated methanol extraction on soil samples

    The automatic dilution function can dilute the sample up to 100 times
