High signal to noise ratio is possible to analyze the parameters of low content of the sample. Built in wavelength calibration to ensure smaller difference between stations difference and better long-term stability. The tester equipped with a temperature control device,Read more >

KN-5185 ICP for used Lube Oils

22 elements in used lubricating oils and in base oils, and it provides rapid screening of used oils for indications of wear. Test times approximate a few minutes per test specimen, and detectability for most elements is in the low mg/kg range. In addition, this test method covers a wide variety of metals in virgin and re-refined base oils. Twenty-two elements can be determined rapidly, with test times approximating several minutes per test specimen.Read more >

KN-4951 ICP for Unused Lube Oils

Additive packages are blends of individual additives, which can act as detergents, antioxidants, antiwear agents, and so forth. Many additives contain one or more elements covered by this test method. Additive package specifications are based, in part, on elemental composition. Lubricating oils are typically blends of additive packages, and their specifications are also determined, in part, by elemental composition. This test method can be used to determine if additive packages and unused lubricRead more >

KN-7111 ICP for Middle Distillate Fuels

Trace elemental analysis is used to indicate the level of contamination of middle distillate fuels. Trace metals in turbine fuels can cause corrosion and deposition on turbine components at elevated temperatures. Some diesel fuels have specification limit requirements for trace metals to guard against engine deposits.Read more >

KN-5708 ICP for Crude Oils and Residual Fuels

When fuels are combusted, vanadium present in the fuel can form corrosive compounds. The value of crude oils can be determined, in part, by the concentrations of nickel, vanadium, and iron. Nickel and vanadium, present at trace levels in petroleum fractions, can deactivate catalysts during processing. These test methods provide a means of determining the concentrations of nickel, vanadium, and iron.Read more >

KN-14538 ICP for Biodiesel（B100）

Biodiesel, defined as a mixture of mono-alkyl esters, is produced from a wide range of vegetable oils and animal fats more commonly by a lipid transesterification process [1-3]. Biodiesel can be substituted for petroleum-based diesel fuel (petrodiesel) in virtually any standard unmodified diesel engine [4, 5]. Pure biodiesel or biodiesel blended with petroleum diesel can be used to fuel diesel vehicles, providing energy security and emissions and safety benefitsRead more >

KN-6595 (RDE-AES) Rotary Disc Electrode Atomic Emission Spectrometer

Wear metals and contaminants in a used oil test specimen are evaporated and excited by a controlled arc discharge using the rotating disk technique. The radiant energies of selected analytical lines and one or more references are collected and stored by way of photomultiplier tubes, charge coupled devices or other suitable detectors. A comparison is made of the emitted intensities of the elements in the used oil test specimen against those measured with calibration standards.Read more >

KN-6595P Portable Rotary Disc Electrode Atomic Emission Spectrometer (RDE-AES)

KN-6595P Portable Rotary Disc Electrode Atomic Emission Spectrometer (RDE -AES) which is capable of directly testing the contents of various metallic elements in liquid samples, such as lubricating oil, hydraulic oil, fuel oil, and etc., and finishing the analysis of various elements with a single injection with a single injection within 2 minutes. No sample pretreatments, auxiliary gas or cooling water is needed before and during the instrument is operating. Because of the strong adaptability tRead more >
