Deposit & Surface Analysis (DSA™)

The Deposit & Surface Analysis (DSA) test kit is designed for the measurement of total biological activity in deposits, on biofilm collection devices, in solid products, and on surfaces. The information gained can be used to quickly troubleshoot and optimize a microbial growth control program to curb excess build–up – and over time lead to the prevention of biofilms.

Are you experiencing premature equipment failure due to microbial-influenced corrosion?  By forming and populating biofilms on pipe walls and surfaces, microorganisms can survive biocide treatment and accelerate corrosion. The Deposit & Surface Analysis test kit (DSA) can be used to manage chemical treatment to microbial build-up.  This test kit is designed for the measurement of total microorganisms present on surfaces or in deposits including corrosion products and slimes.  When coupled with any of our other test kits, the user can characterize the level of microbial growth in both the bulk fluid as well as the contacting surface. This test kit is also unique in its effectiveness to quantify the amount of microbiological activity in biologically active filters (BAF) in drinking water pre-treatment.  Conventional microbiological enumeration techniques struggle with quantifying colonizing cells in these filters whereas the LuminUltra Biofilm test kit obtains a direct measurement in minutes!
