KN-4291 GC for Trace Ethylene Glycol in Used Engine Oil

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 engineRead more >

KN-4815 GC Determining Oxygenates in Gasoline

Ethers, alcohols, and other oxygenates can be added to gasoline to increase octane number and to reduce emissions. Type and concentration of various oxygenates are specified and regulated to ensure acceptable commercial gasoline quality. Drivability, vapor pressure, phase separation, exhaust, and evaporative emissions are some of the concerns associated with oxygenated fuels.Read more >

KN-Biodiesel GC Plus Gas Chromatograph

The biodiesel specified shall be mono-alkyl esters of long chain fatty acids derived from vegetable oils and animal fats.Read more >

KN-2163 GC determining Hydrocarbons in LPG

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.Read more >

KN-3612 GC for Analysis of Dissolved Gases in Transformer Oil (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.Read more >

KN-2409 GC for Glycol Impurities in Mono-, Di-, Tri- and Tetraethylene Glycol

The detection is done with the press of a button With the built-in working curve, it can work normally after simple calibration with standard reference oil Dynamic drift correction to improve the stability of the optical system It has export and automatic storage functions Automatic pixel calibration (spectral tracing) Working curve correction Reference line setting Spectral lines were automatically selectedRead more >

KN-7419 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 lubricatinRead more >

KN-5837 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 FuranicRead more >

KN-2042 Solubility Of Asphalt Materials In Trichloroethylene
