Coulometric Karl-Fischer Titration
Disposable vials can be used to take samples for heating vaporization, which is for standard weight solid or quasi-solid samples, such as: plastic particles, toner, inorganic salts, battery separators, liquid crystals, coatings, food, pharmaceuticals, etc. Working principle: The water in the sample is vaporized through the heater, and the water is carried into the reaction bottle by high-purity nitrogen as the carrier gas to participate in the Karl Fischer reaction, so as to obtain the water co

Apparatus for Sulfur Content in LPG
It is used for determining the total volatile sulfur in gaseous hydrocarbons and liquefied petroleum (LP) gases. It is applicable to analysis of natural. processed, and final product materials. Precision has been determined for sulfur in gaseous hydrocarbons in the range of 1mg/kg to 100mg/kg and for sulfur in LP gases in the range of 1mg/kg to 196mg/kg.

ASTM D2420 Hydrogen Sulfide In Liquefied Petroleum (LP) Gases
Liquefied petroleum gases and their products of combustion must not be unduly corrosive to the materials with which they come in contact. The potential personnel exposure hazards of H2S also make the detection and measurement of hydrogen sulfide important, even in low concentrations. In addition, in some cases the odor of the gases must not be objectionable

ASTM D2158 Residues In Liquefied Petroleum (LP) Gases
Control over the residue content (required by Specification D1835) is of considerable importance in end-use applications of LPG. In liquid feed systems residues can lead to troublesome deposits and, in vapor withdrawal systems, residues that are carried over can foul regulating equipment. Those that remain will accumulate, can be corrosive, and will contaminate following product. Water, particularly if alkaline, can cause failure of regulating equipment and corrosion of metals.
