ASTM D2163 Hydrocarbons In LPG By GC
The hydrocarbon component distribution of liquefied petroleum gases and propene mixtures is often required for end-use sale of this material. Applications such as chemical feed stocks or fuel require precise compositional data to ensure uniform quality. Trace amounts of some hydrocarbon impurities in these materials can have adverse effects on their use and processing.

Gel Permeation Chromatography (GPC)
GPC gel purification system has many advantages such as high purification rate, simple operation, convenient maintenance, safety and reliability. It is mainly used in the pre-treatment and purification process of samples for the detection of pesticide and veterinary drug residues, polycyclic aromatic hydrocarbons, and polychlorinated biphenyls. It is widely used in the fields of agricultural products, food, environment and life sciences.

ASTM D3162 Dissolved Gases In Transformer Oil By GC TOGA
Transformer oil is a highly refined mineral oil used in electrical transformers. It has excellent insulating properties, suppresses corona and arcing, and serves as a coolant. In case of electrical errors, the oil breaks down to gases, which identity and content can be related to the type and severity of the electrical fault. This information is very useful in the preventative maintenance program.

ASTM D5837 Apparatus for Furanic Compounds by HPLC
KN-5837 Furanic Compounds by HPLC conforms to ASTM D5837 Standard Test Method for Furanic Compounds in Electrical Insulating Liquids by High-Performance Liquid Chromatography (HPLC). Furanic compounds are generated by the degradation of cellulosic materials used in the solid insulation systems of electrical equipment. Furanic compounds which are oil soluble to an appreciable degree will migrate into the insulating liquid. High concentrations or unusual increases in the concentrations of Furanic compounds in oil may indicate cellulose degradation from aging or incipient fault conditions.

ASTM D7419 HPLC for Total Aromatics and Total Saturates
KN-7419 HPLC for Total Aromatics and Total Saturates conforms to ASTM D7419 Standard Test Method for Determination of Total Aromatics and Total Saturates in Lube Basestocks by High Performance Liquid Chromatography (HPLC) with Refractive Index Detection. The composition of a lubricating oil has a large effect on the characteristics and uses of the oil. The determination of saturates, aromatics and polars is a key analysis of this composition. The characterization of the composition of lubricating oils is important in determining their interchangeability for use in blending etcetera.

EN14110 Methanol Content In Fatty Acid Methyle Esters By GC
the sample is heared at 80℃ in a hermetically sealed vial to allow desorption of contained methannol into the gas phase.when equilibrium is reached,a defined part of the gas phase is injected into a gas chromatograph,where methanol is detected with a flame ionisation detector.normally methanol is the only peak in the chromatogram.

ASTM D4291 Trace Ethylene Glycol In Used Engine Oil By GC
Leakage of aqueous engine coolant into the crank case weakens the ability of the oil to lubricate. If ethylene glycol is present, it promotes varnish and deposit formation. This test method is designed for early detection to prevent coolant from accumulating and seriously damaging the engine
