KN-3237 AAS for Testing Lead in Gasoline

The gasoline sample is diluted with methyl isobutyl ketone and the alkyl lead components are stabilized by reaction with iodine and a quaternary ammonium salt. The lead content of the sample is determined by atomic absorption flame spectrometry at 283.3 nm, using standards prepared from reagent grade lead chloride. By the use of this treatment, all alkyl lead compounds give identical response.Read more >

KN-AAS Flame Furance Atomic Absorption Spectrophotometer

When fuels are combusted, metals present in the fuels can form low melting compounds that are corrosive to metal parts. Metals present at trace levels in petroleum can deactivate catalysts during processing. These test methods provide a means of quantitatively determining the concentrations of vanadium, nickel, iron, and sodium. Thus, these test methods can be used to aid in determining the quality and value of the crude oil and residual oil.Read more >

AA-1800C Atomic Absorption Spectrophotometer

atomic absorption spectrophotometer is now widely used in scientific research, quality control, disease control, environmental protection, metallurgy, agriculture, chemical industry .Hardware and software design of innovation to ensure the accuracy, safety, ease of use in the analysis of samples, equipment maintenance, simple and convenient.Read more >

KN-1840 UV-VIS Spectrometer

KN-1840 UV-VIS Spectrometer conforms to ASTM D1840 Standard Test Method for Naphthalene Hydrocarbons in Aviation Turbine Fuels by Ultraviolet Spectrophotometry. This test method for naphthalene hydrocarbons is one of a group of tests used to assess the combustion characteristics of aviation turbine fuels of the kerosene boiling range. The naphthalene hydrocarbon content is determined because naphthalenes, when burned, tend to have relatively larger contribution to a sooty flame, smoke, and thermRead more >

KN-FTIR Spectrometer for Lubricants

Lubricant oils exhibit various chemical changes during their life time. This starts by simple changes such a fuel dilution of the fuel used or the uptake of soot (ASTM E2412) from the combustion. Numerous chemical reactions with combustion products lead to oxidation (ASTM D7414), nitration (ASTM D7624) or sulfation (ASTM D7415) of the lubricant and can be summarized as degradation products. To enable cycle times known from modern lubricants a wide variety of additives are added. These additivesRead more >

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 capiRead more >

KN-1945 GC for Analysis of Natural Gas

This GC is of significance for providing data for calculating physical properties of the sample, such as heating value and relative density, or for monitoring the concentrations of one or more of the components in a mixture.Read more >

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 >
