ASTM D5134 Petroleum Naphthas through n-Nonane by Capillary GC
KN-5134 GC for Detailed Analysis of Petroleum Naphthas conforms to ASTM D5134 Standard Test Method for Detailed Analysis of Petroleum Naphthas through n-Nonane by Capillary Gas Chromatography and ASTM D6733 Standard Test Method for Determination of Individual Components in Spark Ignition Engine Fuels by 50-Metre Capillary High Resolution Gas Chromatography. A representative sample of the naphtha is introduced into a gas chromatograph equipped with a methyl silicone bonded phase fused silica capillary column. Helium carrier gas transports the vaporized sample through the column in which the components are separated. Components are sensed by a flame ionization detector as they elute from the column. The detector signal is processed by an electronic data acquisition.

ASTM E2409 GC for Glycol Impurities in Mono-, Di-, Tri- and Tetraethylene Glycol
KN-2409 GC for Determination Glycol Impurities in Mono-, Di-, Tri- and Tetraethylene Glycol. A gas Chromatograph determines the glycol impurities in Mono-, Di- Tri- and Tetraethylene Glycol (MEG, DEG, TEG and TeEG) in the range of 5 to 3000 mg/kg. Knowledge of the impurities is required to establish whether the product meets the requirements of its specifications.

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

ASTM D4815 Oxygenates In Gasoline By GC
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.
