Spectro Oil

Elemental Analysis ICP Spectrometry

Determination of additive elements, wear metals and contaminants in used lubricating oils by Inductively Coupled Plasma (ICP) Atomic Emission Spectrometry. This test provides a rapid screening of used oil for wear indications.

TAN Total Acid Number

This test measures the measurement of the acidic constituents in oils and is reported in milligrams of potassium hydroxide per gram of sample.

Viscosity

This test determines the kinematic viscosities of liquid petroleum products and hydraulic fluids at 40°C and 100°C. The apparatus consists of four calibrated tubes mounted in an oil bath maintained at a constant temperature.

Water by Karl Fischer

This test is used to determine the water content in petroleum products by automatic coulometric Karl Fischer titration, using an oven.

SEM

Debris to be analysed is placed in the SEM and bombarded with electrons which release X rays characteristic of the element that they hit. These X-rays are used to determine the elemental composition of the alloy.

Debris Analysis

This test covers the analysis of wear contaminants from oil wetted surfaces in the oil lubrications systems of turboprop, turbofan or APU engines.This is accomplished by analysing the residue obtained from flushing the oil filter in accordance with the method.

Flash Point - Go / No-Go

This test is used to determine the closed cup flash point by the go/no go method using the Setaflash Tester in the temperature range of 30^oC to 300^oC.

NAS 1638 Particle Count

The sample is pumped through a sensor, which counts and sizes the particles. A 100ml of sample is counted and the particles are grouped into various size ranges. The results are assessed against NAS 1638 to give ratings which determine the cleanliness of the fluid.

Sulphur and Chlorine

This test is designed to determine the Sulphur and Chlorine content in liquid petroleum products.

Chloro Fluoro Hydrocarbons by Gas Chromatography

This test determines the concentrations of chloro-fluoro hydrocarbons in oils and hydraulic fluids. It is an indication of the contamination by compounds used for cleaning or degreasing component surfaces.

Water test by Crackle

This test determines the presence of water in new or used oils. Confirmation of the amount of water may be determined by other methods.

Visual Appearance

This test is used to describe the visual appearance of petroleum products in terms of clarity, brightness and free water.

RULER

This test measures the antioxidants in petroleum products for the determination of remaining useful life. The normal range is 0% - 100%.

Fuel Dilution by Gas Chromatography

This test is used to determine fuel dilution as percentage by weight in lubricating oil.

Neutralisation Number / Titration

This test is used to determine the acidic constituents by colour titration, in petroleum products that are soluble or nearly soluble in mixtures of toluene and isopropyl alcohol. It may also be used to determine basic constituents.
