ALERT One is a standalone, portable analyzer for rapid E. coli quantification in manually collected samples. Palm-sized, this rugged field equipment greatly simplifies measurements by minimally trained personnel.
ALERT One performs automatic incubation, optical monitoring (multispectral absorbance, and fluorescence), and signal analysis, providing rapid E. coli, total/fecal coliforms, and enterococci measurements that are displayed on a small, integrated screen.
Measurements stored in the device can then be exported via USB-C port.
While traditional methods bring samples to the lab, ALERT One brings the lab to the samples. Thus, it greatly optimizes the process by:
- eliminating the need for sample refrigeration during transport (prior to standard laboratory measurements) and reducing errors due to sample degradation;
- minimizing time-to-result and measurement costs;
- significantly simplifying water quality monitoring, especially at remote sites and in disaster zones;
- enabling rapid response to public health emergencies.
A portable, multi-sample version (Alert LAB) and a fully automated in situ version (Alert System V2) are also available.
Applications
ALERT One can be used in a wide variety of contexts to confirm the presence of E. coli, total coliforms, fecal coliforms, and enterococci, as well as to quantify their concentrations in any type of water, including:
- lakes,
- reservoirs,
- rivers,
- coastal waters,
- intake sites,
- water treatment plants,
- fish and aquaculture farms,
- agriculture, irrigation water,
- wastewater re-use and recycling,
- public and private swimming pools.
Main benefits
- ALERT One is versatile: it can be used anywhere in the world, including in the most inaccessible areas, to quantify E. coli concentrations in any type of water;
- ALERT One is autonomous: it can operate through a USB charger or battery pack;
- ALERT One is easy to use: anyone can be trained in a matter of minutes;
- ALERT One is portable: as the world's first handheld microbiology analyzer, it can easily be carried in a backpack, is accepted on commercial airplanes, and can even be powered on-the-go from a vehicle;
- ALERT One is fast and accurate: it can perform bacteria/100ml quantifications in as little as 2 hours, with high accuracy and repeatability, as confirmed by numerous side-by-side tests against approved laboratory methods;
- ALERT One is recognized and officially approved: it has successfully passed WHO and UNICEF verification under the Joint Monitoring Programme* (report available upon request) and tests by numerous other independent scientific studies.
