Portable infrared analyser can be used in new ASTM method to measure recoverable oil and grease and nonpolar material
ASTM has recently approved a new standard test method for measuring total oil and grease (TOG) and total petroleum hydrocarbon (TPH) concentration levels in water and soil.
ASTM Method D 7066 - 04 covers the use of dimmer/trimer of chlorotrifluoroethylene (S-316) for analysis of recoverable oil and grease and nonpolar material by infrared determination.
This new ASTM method approves S-316 as a replacement solvent for Freon for this analysis.
The InfraCal 10mm quartz cuvette holder analyser, model CVH, manufactured by Wilks Enterprise, was one of the infrared instruments used for developing this new ASTM test method.
The model CVH is an easy to use, portable, fixed filter infrared analyser that quickly determines TOG or TPH levels in water and soil samples in less than 10-15 minutes, including extraction procedure.
Concentration levels as low as 1-2 parts per million (ppm) to well over 500ppm can be measured.
The Infracal model CVH is portable, weighing under 2.3kg.
It operates from a 12 volt power supply making it ideal for on-site field or laboratory use.
The model CVH is direct reading and microprocessor-controlled with simple pushbutton operation for easy operation.
It requires minimal training or knowledge of infrared analytical techniques.
The analyser is said to be ideal for wastewater applications and remediation site clean ups.
