Miscellaneous Techniques

 

Part of the success of our company comes from being prepared to invest in new equipment and expertise when the needs arise. Should you require analytical services that are not already detailed in this website then please contact us to discuss your needs. Our highly experienced team of analysts, coupled with our existing equipment and instrumentation, allow Ultra Trace to offer an extensive range of analytical techniques. Some of the less common methods are listed below. This list is by no means exhaustive.

Moisture (Method Code : GEN001)
Sample is oven dried at 105°C. Moisture is determined gravimetrically.

Loss on Ignition (Method Code : GEN002)
Sample is routinely ignited at 1000°C. LOI can be analysed at other temperatures if requested.

Bulk Density (Method Code : GEN003)
The sample is weighed suspended in air and in water.

FeO Analysis (Method Code : GEN004)
Sulphuric / Hydrofluoric Acid digest, FeO Determined volumetrically.

Neutralising Value (Method Code : GEN005)
By acidification and determination of acid consumption.

Organic Solvents Analysis (Method Code : ICP601)
A number of elements may be determined in organic solvents by ICP-OES.

Multi Element Scans (Method Code : SCAN1)
Samples are digested using suitable acid digests and analysed for up to 61 elements.

Chondrite Normalisation of Rare Earth Elements (Method Code : CHONDRITE1)
Available after Mixed Acid Digest and ICP-MS analysis.

Preparation of Composites (Method Code : CMP01)
Equal amounts of each pulverised sample are weighed and thoroughly mixed.

Preparation of Composites (Method Code : CMP02)
A portion of each sample is obtained by riffle splitting. These portions are then combined prior to pulverising.

Carbon and/or Sulphur by Total Combustion (Method Code : TC002)
Samples are heated to 1400°C . The resultant CO2 and SO2 is measured by Infrared absorbtion.
