Technology

We have taken industry standards and embedded them in the measurement, sampling handling, statistical analysis, and data collection processes. The QwikLite® 200 Biosensor System uses patented methods to rapidly determine toxicity of potential contaminants of both inorganic and organic varieties.

The testing process is simple and can be done in any temperate location. State of the art miniature optics and electronics are used to analyze each sample separately. Quality control and sample integrity are ensured via the bar coded disposable test kits, menu driven guidance of EPA methods and laboratory procedures, and industry standards for completing reports. These include:

EPA procedures and requirements for sampling methods and measurements are part of the Assure QwikLite® 200 Biosensor System, and follow EPA Methods for Measuring Acute Toxicity EPA-821-R-02-012, -013, -014.
Bioluminescence: total light emitted and spectral characteristics of selected species of marine plankton is measured and compared to a standard or control sample in each test.

Current Process for Toxicity Testing: 7-8 Days

Day	Steps	Activities
1	Need	Operations or protocols require toxicity testing. Client engages professional services to conduct testing and prepare report.
2	Sampling	Technician or consultant goes to site to collect sample. Sample(s) recorded and taken to test lab. Lab begins toxicity testing per protocols.
3	Dose - Test	Toxicity testing on live research organisms. Observations and notes.
4	Testing	Toxicity testing on live research organisms. Observations and notes.
5	Testing	Toxicity testing on live research organisms. Observations and notes.
6	Measure-Reporting	Toxicity testing concludes. Measurements of LD50 and notes. Data provided to professional services firm.
7	Reporting	Data reviewd by professional services firm. Report developed per protocols. Results and conclusions included in final report.
8	Reporting	Client receives report.

QwikLite™ Process for Toxicity Testing: 1-3 Days

Day	Steps	Activities
1	Need-Sample-Dose	Client's protocols require toxicity testing. Sampling done on site. Plankton are dosed per menu-driven specific protocols and procedures. Report is started.
2	Testing	After 24 hrs, one or more samples provide LD50 data. Testing may conclude or continue per protocol. Data automatically sent to report system with completed statistics.
3	Measure-Reporting	Toxicity testing concludes. Measurements of LD50 and data for all samples done automatically. Statistics automatically included in final report. Client makes notes about results and report is complete.
