HKL-2385 Hydrogen Sulfide Analyzer
Overview
HKL-2385 Hydrogen Sulfide Analyzer conforms to the ASTM D2385 Standard Test Method for Hydrogen Sulfide and Mercaptan Sulfur in Natural Gas (Cadmium Sulfate Iodometric Titration Method). This test method covers the determination of hydrogen sulfide and mercaptan sulfur in natural gas. It is applicable over the concentration range from 0 to 5 grains of hydrogen sulfide (approximately 11 mg/m³) and 0 to 1 grain of mercaptan sulfur per 100 cubic feet (2.832 cubic meters) of natural gas. Natural gas and its combustion products must not cause undue corrosion to the materials they come into contact with, which is why the determination of hydrogen sulfide and other sulfur compounds is essential.
Principle
The procedure involves using an excess zinc acetate solution to absorb hydrogen sulfide (H₂S) from a gaseous sample, generating zinc sulfide precipitate. Subsequently, an excess iodine solution is added to oxidize the generated zinc sulfide, and the remaining iodine is titrated with a sodium thiosulfate standard solution.

FAQ
Q1: What standards does this product (HKL-2385 Hydrogen Sulfide Analyzer) comply with?
A: HKL-2385 Hydrogen Sulfide Analyzer conforms to the ASTM D2385 Standard Test Method for Hydrogen Sulfide and Mercaptan Sulfur in Natural Gas (Cadmium Sulfate Iodometric Titration Method). This test method is concerned with the measurement of hydrogen sulfide and mercaptan sulfur in natural gas. It can be used for the concentration range of 0 to 5 grains of hydrogen sulfide (approximately 11 mg/m³) and 0 to 1 grain of mercaptan sulfur per 100 cubic feet (2.832 cubic meters) of natural gas.
Q2: The working principle of HKL-2385 Hydrogen Sulfide Analyzer for testing?
A: Hydrogen sulfide (H₂S) in the gas sample is absorbed by using a high amount of zinc acetate solution that results in the formation of zinc sulfide precipitate. After that, an extra amount of iodine solution is added to oxidize the zinc sulfide formed, and the leftover iodine is titrated by using the standard sodium thiosulfate solution.
Q3: Significance and use of HKL-2385 Hydrogen Sulfide Analyzer?
A: Natural gas and the products produced by its combustion should not cause excessive corrosion to the materials with which they come into contact. Therefore, the measurement of hydrogen sulfide and other sulfur compounds is one of the key issues.
Q4: How can I obtain the user guides and technical documentation for the products?
A: Certainly. We offer full digital resources for each of our products that range from detailed user manuals and quick start guides to application case studies.
