99.5% sensitivity when detecting harmful biological organisms
There are several approaches to control the proliferation of pathogens in the industrial waters. It is possible to prevent the appearance of bacteria by using large quantity of chemicals or disinfecting methods. However, this method represents significant monetary costs, as well as serious indirect impacts such as premature wear of the infrastructure and harmful environmental releases. An alternative approach is to do the point analysis of water to determine its bacterial content, in order to assess the amount of chemicals needed.
Traditionally, only specialized laboratories had competencies to perform those kind of analysis by bacterial culture or by quantitative PCR method. Since 2012, alternative products have emerged on the market. Those products are disposable test, operated similarly to a pregnancy test. They employ a simple detection method called Lateral flow immunochromatographic assay. Each method, described above, possess certain disadvantages, which pushed scientists to search a new, more efficient and practical solution.
SPIBIO introduced the products of a new generation. SPIBIO name technology addresses weak points of each previous detection method, and provides businesses with a reliable and economical monitoring solutions.
The comparison of the technologies are presented in the table below
|Detection method||Culture||qPCR||Lateral flow immunochromatographic assay||Technology BIO-ALERTE|
|Speed||7 to 14 days||48 hours||15-25 mins||30 mins|
|Detection limits (total)||100 to 500 CFU||60 to 250 CFU||100 to 200 CFU||10 CFU|
|Robustness (sensitivity)||≈ 70%||≈ 95%||Varies greately between the brands (≈ 80%)||≈ 99%|
|Frequency of testing||Point, 1 per measurement||Point, 1 per measurement||Point, 1 per measurement||Daily, 1 per day|
|Handling requirements||An employee to perform sampling, ship to laboratory, follow-up the process and control the results.||An employee to perform sampling, ship to laboratory, follow-up the process and control the results.||Technician to perform sampling and analysis||No human intervention; Fully autonomous|
It can be seen from the table that contrary to the laboratories and test sticks, the technology has a number of advantages such as:
- It combines both high reliability and fast results on-site
- It allows monitoring environments on the daily basis
- It eliminates expenses for stuff labor and shipping.
- Its reliability is above of the industry standards.
