Low Pressure Reduced Sulfur (0.1 to 100 PPB)
Sulfur gases can be collected and analyzed using Silonite coated samplers and canisters. Sulfur compounds have been shown to be stable in Silonite canisters for 1-2 weeks, allowing sucient time to perform laboratory analysis, even if samples must be shipped over long distances after sampling. Odor threshold levels can be met using GCMS or GC/CLD (Chemiluminescence Detector) when preconcentrating 10 to 200cc of sample.
Maximum stability of H2S and Methyl Mercaptan requires relative humidities to be below 20%. When the relative humidity is above 20%, excess water can be absorbed using Bottle-Vac samplers that contain a small amount of anhydrous Silica gel. Just enough Silica gel is used to absorb most of the water without affecting H2S or Methyl Mercaptan concentrations, allowing these compounds to be stable for weeks. When monitoring a wider range of sulfur compounds, Entech recommends the use of two different samplers; the 29-BV500-H2S or 29-BVL1-H2S for H2S and Methyl Mercaptan, and a standard Bottle-Vac or Silonite coated MiniCan or larger Silonite canister for all other compounds. Silonite coated cylinders are also available for high-pressure refinery gas sampling environments and long-term storage requirements.
微量还原态硫 (0.1~100PPB)
硫化物气体可以用硅烷化涂层的采样器和采样罐。硫化合物已被证明在锡兰的canisters中稳定1-2周,允许有足够的时间进行实验室分析,即使样品必须在取样后长距离运输。当预浓缩10 - 200cc样品时,可以使用GCMS或GC/CLD(化学发光检测器)来达到气味阈值。
