What is the OSS Total Petroleum Hydrocarbon (TPH) Method?

The OSS TPH Method makes the measurement process safer, faster, more cost effective and enables identification of oils.

This breakthrough method to measure Total Petroleum Hydrocarbons (TPH) in water and wastewater has significant advancements over traditional Liquid-Liquid extraction methods. The method is also referred to as measuring Polar and Non-polar portions of total oil and grease. When used in conjunction with the OSS TOG test method, the new TPH method provides the user with a complete system to cost effectively, safely, rapidly and accurately measure oil in water systems.

Use Our TPH Method in a Wide Range of Applications

OSS TPH methodology is available for use in a wide range of applications, including wastewater and process water testing applications, water testing laboratories, major chemical complexes and government environmental regulatory agencies. This new method dramatically reduces the amount of solvent needed to determine oil fractions within water samples and represents a dramatic leap forward in safety, speed, simplicity and accuracy.

Oil Identification

Identify the Source

OSS Clearshot technology, in combination with FTIR capabilities, can be used to create individual oil product “fingerprint” catalogues. These individual unique characteristics of different oils are used to automatically identify which oils are present in the sample being analyzed, with no additional steps required.

Prevent Quality Issues

OSS will work with your team to identify the oil products in samples being analyzed. In production facilities, you can quickly identify the source of an oil problem and take immediate action. Knowing the source can prevent poor process performance, substandard product quality, and costly fines.
