KN-323Z Automatic Reid Vapor Pressure Bath
Vapor pressure is an important physical property of volatile liquids. This test method is used to determine the vapor pressure at 37.8°C (100°F) of petroleum products and crude oils with initial boiling point above 0°C (32°F).
Vapor pressure is critically important for both automotive and aviation gasolines, affecting starting, warm-up, and tendency to vapor lock with high operating temperatures or high altitudes. Maximum vapor pressure limits for gasoline are legally mandated in some areas as aRead

KN-5453 Ultraviolet Fluorescence Sulfur Tester
Some process catalysts used in petroleum and chemical refining can be poisoned when trace amounts of sulfur bearing materials are contained in the feedstocks. This test method can be used to determine sulfur in process feeds sulfur in finished products, and can also be used for purposes of regulatory control.Read

KN-7621 Apparatus for Hydrogen Sulfide in Fuel Oils
KN-7621 Apparatus for Hydrogen Sulfide in Fuel Oils conforms to ASTM D7621 Standard Test Method for Determination of Hydrogen Sulfide in Fuel Oils by Rapid Liquid Phase Extraction. A weighed test specimen is introduced into a heated test vessel containing a diluent base oil. Air is bubbled through the oil to extract the H2S gas. The air with the extracted H2S is passed, via a vapor phase processor (Procedure A only), to an H2S specific electro-chemical detector enabling the H2S content of the aiRead

KN-300R Octane Number of Spark-Ignition Engine Fuel
Research O.N. correlates with commercial automotive spark-ignition engine antiknock performance under mild conditions of operation.
Research O.N. is used by engine manufacturers, petroleum refiners and marketers, and in commerce as a primary
specification measurement related to the matching of fuels and engines.
Empirical correlations that permit calculation of automotive antiknock performance are based on the general equation:Read

KN-1500 Colorimeter for Petroleum Products
Determination of the color of petroleum products is used mainly for manufacturing control purposes and is an important quality characteristic, since color is readily observed by the user of the product. In some cases, the color may serve as an indication of the degree of refinement of the material. When the color range of a particular product is known, a variation outside the established range may indicate possible contamination with another product. However, color is not always a reliable guideRead

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

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
