Advanced coolant analysis is performed not only to monitor the condition of the coolant, but give a clear picture of what is happening in the cooling system.
Serious mechanical problems can be predicted and averted by detailed evaluation of your coolant condition. Advanced coolant analysis should be done with regularity to obtain the full benefit.
Test Descriptions
Advanced coolant analysis includes the basic coolant package as well as:
Reserve Alkalinity (ASTM D1121)
- The reserve alkalinity is an indication of the ability of the coolant to neutralize acids. In essence, it is a measurement of the quantity of defensive buffer (i.e. preemptive Rolaids) still remaining in the coolant.
- Milliliters of hydrochloric acid required to obtain a pH of 5.5 in a 0.33 fl.oz. sample. Trending the reserve alkalinity (and inhibitor additives) helps to predict when the coolant will become too acidic.
Spectrometry/Inductively Coupled Plasma/ICP (ASTM D6130)
- Typically identifies 3 groups of elements present in a coolant sample that require monitoring for optimal coolant performance.
- Wear Elements
Lead, Copper, Tin, Aluminum, Silver and Zinc are often the result of the wear or corrosion of surfaces within the cooling system. - Contaminants
Calcium and Magnesium can result from foreign substances present in hard or untreated water. - Additive elements
Phosphorus, Silicon, Boron, Potassium, Molybdenum and Sodium are present in additives and inhibitors designed to enhance coolant properties.
- Wear Elements
Optional Tests
Total Suspended Solids (TSS)
- TSS is based on the Standard Methods (APHA et al., 2005) procedure for total suspended solids determination. Fluid life reports the total suspended solid present in the coolant sample in mg/L. This test requires a minimum 3.5 fl.oz. sample.
