Corrosion, especially of metals, is a global problem that costs an estimated 2.5 trillion USD each year in direct and indirect costs. Of this, as much as 1 trillion USD can be ascribed to microbiologically influenced corrosion.
Given the tremendous cost of corrosion, in time, personnel and resources, Microbial Insights has developed purpose built tools to help identify and monitor for conditions that promote corrosion. One such tool is QuantArray® MIC.
QuantArray® MIC, an advanced qPCR method, rapidly detects and quantifies key microorganisms and functional genes responsible for microbiologically influenced corrosion (MIC) and oilfield souring in a single analysis.
ACCURATE
Direct analysis of sample DNA removes the need to grow the bacteria thus eliminating biases associated with traditional approaches (e.g. plate counts and BARTs).
QUANTITATIVE
Absolute quantification of concentrations of total bacteria, total archaea, and specific microbial groups to monitor abundances over time or in response to treatment. Results reported as cells/mL, cells/g, etc.
SENSITIVE
Practical Detection Limits (PDL) are as low as 100 cells per sample with a dynamic range over seven orders of magnitude.
SPECIFIC
Target specific bacterial groups (e.g. sulfate reducing bacteria, methanogens) associated with MIC.
COST-EFFECTIVE
In a single analysis, quantify total bacteria, total archaea, and a broad spectrum of common MIC microorganisms (e.g. SRB, SRA, methanogens, IRB, FeOB, etc.) Same accuracy and turnaround time as CENSUS®qPCR but more comprehensive and even more cost-effective.
CUSTOMIZABLE
Assays are available for quantification of MIC associated microbes for which traditional assays are not available, and custom assays can be developed to fit your needs.
FLEXIBLE
QuantArray® MIC analysis can be performed on almost any type of sample (water, solids, corrosion coupons, swabs, pigging debris, scrapings, Bio-Traps®, and others).

QuantArray® MIC provides simultaneous quantification of key organisms and functional genes involved in MIC, as well as oilfield souring, proving a more comprehensive assessment. Evaluation of the microorganisms present within a system permits managers to:
All of the organisms listed above are included in a single QuantArray® qPCR analysis.
– QuantArray®-MIC was performed on swab samples from internally pitted and adjacent non-pitted areas of pipeline components as part of a multiple lines of evidence approach to evaluate microbiologically influenced corrosion (MIC).
