Sonic Concentration Analyzer

Non-contact Concentration and Setting Rate of Suspensions and Emulsions

The Sonic Concentration Analyzer is an easy to use system that can measure the stability and relative concentration of suspensions and emulsions. The computerized system takes ultrasonic measurements of a sample, then produces a graph of the concentration profile. The containerized sample cane be repeat ably tested over time without disturbing the sample liquid.

Functions

	Dispersion and Suspension Stability Testing
	Liquid Concentration Measurement
	Quality Control Testing
	Shelf Life Testing
	Analysis of Effectiveness of De-emulsifying Chemicals
	Study of flocculation

Key Benefits

	Eliminates visual/manual inspection such as freezing and sectioning
	Assures stability of suspensions
	Sensitive, consistent concentration readings
	Nondestructive, rapid analysis quickly detects any settling
	Sample containers may be removed, stored and retested
	Monitors long-term stability without tying up the instrument
	User friendly, menu-based software for the PC

Principle of operation

The Sonic Concentration Analyzer (SCA) is an ultrasonic instrument designed to quantify the stability of suspensions and the concentration of emulsions and liquid mixtures. The SCA scans a pair of ultrasonic sensors along the outside of a sample container, taking time-of-flight (TOF) measurements at discrete vertical increments. TOF is the time required for the ultrasonic signal to travel between the sensors, passing through the sample under test. By comparing the measured TOF to a TOF vs. concentration calibration curve, the SCA generates a graph of the concentration profile of the sample. After the TOF measurements are complete, the sample container can be removed from the water bath, stored, and re-tested over a long period of time. The settling rate or stability of the sample can be measured quickly and precisely. The SCA can also be used, without scanning, as a quick and non-destructive measure of component concentration in non-settling samples.
