This instrument is used for detecting liquefiedPetroleum GasIn the Chinese contextHydrogen sulfideYes or no, inspectionSulfur HydrogenThe minimum is 4mg/m³.3, If methyl mercaptan is presentAcetic Acid, LeadTemporary yellow spots appear on the test strips, but they completely disappear within 5 minutes, liquefactionOil & GasOther sulfur compounds in the medium do not interfere with this test. Under experimental conditions, the vapor of liquefied gas is passed through a moistenedAcetic Acid, LeadTest stripsAcetic Acid, LeadAndHydrogen sulfideReactive to form lead sulfide, which exhibits a color change on the test strip, based onSulfur HydrideThe concentration level determines the depth of the test strip color, ranging from yellow to black.

5. The equipment includes 1 set of glassware, 1 stainless steel connector with a needle valve, 1 flowmeter 0-3L/min, and 1 accessory for glassware support.
6. Sensitivity of 4mg/m³3。
7. Sampling: Due toHydrogen sulfideThe chemical reactivity and physical absorbency require that the instrument and sample source be directly connected for on-site testing, rather than transferring the sample to the laboratory for measurement. Experience shows that using strictly clean sample capsules (even if they are made of stainless steel),Sulfur HydrideAlso commonly exhausted; conversely, even without liquefied gasHydrogen sulfideWhen using sample shells that have not been properly cleaned (previously used with contents),Sulfur Hydride(Samples), it would also be considered to contain sulfur content. This fact is intended to indicate that the laboratory obtainedSulfurated hydrogenThe content is unreliable.
8. Testing Process: Connect the experimental equipment and sample source with clean stainless steel pipes (keep the pipes as short as possible), and gently flush the pipelines and equipment for about 1 minute.
Rapidly moisten a strand with distilled waterAcetic AcidLead test strips are hung on the hook in the measuring room and exposed for 2 minutes under these conditions. Remove the strip, compare the experimental test strip with the untested wet strip, and draw a conclusion.
