Chem-TechTM Laboratories is a pioneer in providing Engine Oil analysis services. For the past 19 years Chem-TechTM has been providing Engine oil analysis services to leading multinational companies for their oil condition monitoring & predictive maintenance programs.
Utilizing various sophisticated instruments and test methods, Chem-TechTM Laboratories carry out testing of engine oil, looking for the minute sign of information or problems which may lead to machine maintenance or downtime due to failure.
Chem-TechTM Engine Oil Analysis programs will help you to:
Chem-TechTM Engine Oil Analysis programs monitor parameters that are harmful to your engine & may lead to failure and malfunctioning, these mainly include:
Chem-TechTM offers Engine Oil Testing in two main packages:
Basic package includes preliminary monitoring of Engine Oils - Total Base Number, Change in Viscosity, Water Content & Soot. Advanced testing monitors Wear Metal analysis, Determination of Contaminants, Determination of Depletion of Additives, Ferrography.
Apart from Used oil analysis Chem-TechTM Laboratories capability includes Specification Testing of Engine oil aswell. Chem-TechTM carries out testing of Engine oil as per internationally accepted ASTM,ISO & IS Test Standards.

Kinematic Viscosity is a measurement of the resistance of the oil to flow through a capillary tube of the viscometer. It is the most fundamental property of a lubricant. Viscosity of lubricants is measured in case of fresh oils to check the Grade of the oil . in case of used oils it gives idea about change in physical properties due to oxidation, dilution or any external contamination. It is the most fundamental property for testing of any lubricant or petroleum product.
Methods Adopted by Chem-Tech for Viscosity Determination:
Total Base Number determines the amount of alkaline / basic component present in Oil. Its is a very fundamental test for Engine Lubricants. It determines the ability of oil to neutralize acids generated in the oil due to Oxidation, Combustion by products or external contamination.
Methods adopted by Chem-Tech Laboratories for Base Number Analysis:
Total Acid Number determines the amount of acid present in the lubricant. Acidity of the lubricant increases due to the stresses or environmental factors affecting the lubricant. Excess amount of acid in the lubricant will lead to corrosion or failure of equipment.
Methods adopted by Chem-Tech Laboratories for Acid Number Analysis:
Soot Content is the measurement of carbon / sooty particles generated due to incomplete combustion of fuel. Higher Soot generation leads to degradation of Oil.
Methods adopted by Chem-Tech for Soot Content Determination:
Water or Moisture is the most common contaminant in any lubricant or petroleum product. Monitoring the level water in sample is of prime importance to avoid malfunctioning of the equipment or machine.
Water content in petroleum products can be determined by following 4 test methods:
Methods Adopted by Chem-Tech for Water / Moisture Content Determination:
Elemental Analysis by ICP determines the amount of Wear metals , Contaminant Metals and Additive Metals present in a Lubricant. Elemental Analysis can detect upto 24 elements in the lubricant. These includes all the particles present in oil upto 5-10 microns in size.
It gives an idea about the amount of Wear and Contamination in the Lubricant. It is one of the primary tests conducted for Trend Analysis or Predictive Maintenance of the Equipment.
Test Methods adopted by Chem-Tech for Elemental Analysis:
Oxidation measurement by FTIR is the measurement of degradation of Oil due to the operating conditions of the equipment and breakdown of additives in the Lubricant or Oil. Increase in Oxidation directly affects the acidity of the oil. Increase in the Oxidation of Oil increases the acidity of the lubricant.
Methods adopted by Chem-Tech Laboratories for Oxidation Analysis:
Nitration is similar to oxidation. Nitration results from the reaction of oil components with Nitrogen Oxides that are produced from the oxidation of atmospheric nitrogen during the combustion process. In addition to causing oil thickening, nitration products are the major cause of the build-up of varnish or lacquer on engine parts. Increase in Oxidation or nitration will lead to Increase in Acid Number, Viscosity and in turn will decrease the Base Number Of the Oil and breakdown of the additives.
Methods adopted by Chem-Tech Laboratories for Nitration Analysis:
Ferrography or Wear debris analysis determines the type of wearing and analyses sample for wear pattern, size and shape of wear elements and also any external contaminants present in a lubricant. Ferrography gives lot of information on the functioning of the equipment. Abnormal wear pattern may indicate possible failure of equipment, improper film forming capacity of oil, inappropriate type and quality of oil used.
