A portable, fixed filter infrared filtometer for measuring unsulphonated matter in linear alkyl benzene sulphonic acids has just been introduced by Wilks Enterprise
The InfraCal Filtometer replaces a time consuming process which uses large amounts of petroleum ether to extract the unsulphonated matter.
With the InfraCal Filtometer a small amount of petroleum ether extract is analysed in minutes.
This new application for the InfraCal Filtometer uses ATR (attenuated total reflection) crystal and fixed filters to measure C-H (hydrocarbon) absorbance.
The extracted nonionics of the unsulphonated matter all possess a hydrocarbon chain.
An aliquot (50ul) of petroleum ether is deposited onto the crystal and the InfraCal measures C-H absorbance proportional to the amount deposited down to .1%.
After solvent evaporation (about three minutes), the C-H concentration is displayed on the analyzer's digital display in less than 30 seconds.
The InfraCal Filtometer weighs less than 5lbs (app 2kg), is a 6.5x6.5x5inches cube in size, and requires just 12volts of DC power for operation.
It is ideal for use directly in the manufacturing area or in the QC laboratory.
User-friendly operation makes it easy for production personnel to operate with minimal training.
