Automating Iodine Adsorption Number Analysis

Automating Iodine Adsorption Number Analysis

Iodine adsorption number of carbon black according to ASTM D1510 Carbon Black provides a challenging matrix for titration. Manual sample filtration, transfer and reagent addition along with small variations in colour change, introduce wide variations in reproducibility, which limit profit margins.

Digestion of samples with PGEs with ULTRAWAVE

Samples with PGE content are chemically inert. They are therefore difficult to prepare for ICP analysis. Platinum Group Elements (PGEs) are considered the most valuable precious metals. For this reason, they are often used for jewelry and ornament purposes. they also play an important role in the automotive catalytic converter...

Chloride in Fuels

Chloride in Fuels

Simplified LPG analysis by ASTM D7994-17 Halides and sulphur in LPG are important factors for corrosion and pollution. Unfortunately, due to the volatile nature of LPG, analysis of these components is more complex than for standard liquid fuels.  Automating analysis with IC provides a range of benefits; Consistent sample introduction...

Determination of the MacMullin number

A valuable way to compare battery separators is to monitor the difference between the resistivity of the separator soaked in the electrolyte and the resistivity of the free electrolyte. The ratio of these two values is the MacMullin number. This Application Note shows how to perform the necessary measurements and...
