A2 Technologies has announced its integrated FTIR analyser designed for the rapid analysis of liquids by FTIR spectroscopy in industries such as petroleum, energy, chemical and food.
Based on A2's ML analyser, the FTIR spectrometer occupies just 8in2 on a lab bench.
The ML with Dialpath technology represents a new approach to the analysis of liquid samples.
The Dialpath technology features a tumbler-like optical head that can be rotated into position to provide one of three, factory set, selectable sample pathlengths between 30 and 250 microns.
To analyse a sample, a drop of the liquid is placed on a stationary infrared-transparent window mounted on the top surface of the analyser, then a second window is rotated into position, thus sandwiching the sample between the two windows.
This creates highly reproducible, fixed sample pathlength between the two windows.
The Dialpath technology offers the user a choice of three different pathlengths, which are specified when the system is ordered.
For lower concentration samples, simply dial in a longer pathlength window set; for samples that are more concentrated, use the shorter pathlength combination.
There is no need to use traditional demountable liquid cells, which can leak, require spacers, may fringe, are difficult to fill and clean, and are particularly difficult to use with more viscous samples.
The Dialpath-equipped ML accommodates samples with a wide range of viscosities.
Cleaning the Dialpath analyser is carried out by rotating the window away from the fixed window and wiping the liquid sample off both windows.
