99,5 % sensitivity when detecting harmful biological organisms
There are several approaches to controlling the proliferation of pathogens in industrial waters. It is possible to prevent the appearance of bacteria by using large quantity of chemicals or disinfecting procedures. However, these methods represent significant monetary costs, as well as serious indirect impacts such as premature wear of the infrastructure and harmful environmental releases. An alternative way 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 process called Lateral flow immunochromatographic assay. All techniques described above possess certain disadvantages, which pushed scientists to search for a new, more efficient and practical solution.
SPIBIO introduced the products of a new generation. SPIBIO name technology addresses weak points of each detection solution previously mentioned, 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||Bio-Alert technology|
|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, shipping to laboratory, following up the process and controlling the results||An employee to perform sampling, shipping to laboratory, following up the process and controlling the results||Technician to perform sampling and analysis||No human intervention; fully autonomous|
Contrary to the laboratories and test sticks, the Bio-Alert technology has a number of advantages such as:
- Combining both high accuracy and fast results on-site.
- Monitoring environments on a daily basis.
- Eliminating staff, labor and shipping costs.
- Entrusting reliability that exceeds current industry standards.
