Kemira Kemsens by Aqsens Q technology

HIGHLY SENSITIVE PATENTED TECHNOLOGY

Highly sensitive technology

Patented detection technology using time resolved fluorescence (TRF) in conjunction with chemical modulators enables us to measure residual inhibitor concentration in the range of 1 to 140ppm (range up to 100 000ppm).

TRF – How it Works

Europium/polymer  complexes fluoresce for around one 1ms. By delaying the measurements by >100µs most background fluorescence such as autofluoresence and light scattering are blocked thus eliminating unwanted interference. AQSENS™ is high performance TRF method for measuring trace amounts of residual polymeric scale inhibitor present in oilfield produced waters with a high degree of accuracy and repeatability.

SIMPLE BY DESIGN

Simple, 3-step process

AQSENS™ in-field test protocol has only three steps. After collecting the samples, you just plug-in the system and it’s ready for measuring. You get your results in just 10 minutes. Testing protocols are factory calibrated to facilitate the ease-of-use and to ensure treatment consistency. There is low level of training needed for operating the system.

Summary specifications

Applications (polymeric and for phosphonate SI ) are used with the Q Reader.They are tolerant to variations in scale inhibitor product formulation as well as variations in produced water.

Typical results  are summarized in the table. And examples of comparisons with HPLC are shown in the two figures.

SI Application TDS Sensitivity Reproducibility Spiked Recovery
Polymeric > 150 000 1 ppm Less than 5 CV% 90 to 110%
Phosphonate > 330 000 0.5 ppm Less than 5 CV% 90 to 110%
