Physical
The following tests are available for water, oil or alcohol-based samples:
Asphaltene Testing (Test #3279)
A filter extraction technique for determining the weight concentration of ashphaltenes as defined by insolubility in normal heptane solvent
Total Suspended Solids (TSS): weight concentration of insoluble solids present in aqueous, hydrocarbon, or paraffinic solutions
- Alcohol Based (Test #4409): emulsions/alcoholic beverages
- Oil Based (Test #4405): wax free petroleum solutions
- Paraffin (Test #4406): waxy petroleum solutions
- Aqueous (Test #4404): water based solutions
Karl-Fischer Titration (Test #1364)
Determines the presence of water in oil based solutions, such as hydraulic oil, paint, varnish, lacquer, and other related products
Viscosity
- Dynamic (Test #445D): The ratio of shear stress to shear rate. The SI unit of dynamic viscosity is the Poise (kg/[m*s])
- Kinematic (Test #445K): The dynamic viscosity normalized by a liquid’s density. The SI unit of kinematic viscosity is the Stoke (m2/s)
pH (Test #pH)
acidity or basicity (alkalinity) of an aqueous solution
Ash Content (Test #482)
Inorganic solids content by burn-off
Turbidity (Test #7027)
Quantifies the reduction in transparency of aqueous solutions caused by undissolved matter
Benchtop Filtration (Test #bench)
Lab simulation of filter performance based on customer requirements and sample type
Inductively coupled plasma optical emission spectroscopy (Test #5185) (ICP-OES), is an analytical technique used for the detection of trace metals.
- ICP-OES can be used for motor oil (and other lubricating oil) analysis.
- Analyzing used motor oil reveals details about how the engine is operating.
- Parts that wear in the engine will deposit traces in the oil which can be detected with ICP-OES analysis.The amount of trace elements in the sample can help to determine whether parts are failing.
- ICP-OES can also determine what amount of certain oil additives remain and therefore indicate how much service life the oil has remaining.
- ICP-OES is also used during production for quality control and compliance with production and industry specifications.
- ICP-OES can be used for waste-water analysis in accordance with EPA standards
Particle size
The following tests are available for water, oil or alcohol-based samples:
Particle size distribution (Test #4407, 4408, 4410)
Quantifies the non-soluble content of fluids from 0.5-400 microns in size. Other particle sizes can be determined based on need. Results from this test method are interpreted both by population-based analysis, and by volumetric-based analysis
Microscopy
The following tests are available for water, oil or alcohol-based samples:
Microscopy / Photography (Test #11117)
Techniques for determining the physical properties of laboratory samples or other objects of interest
