The Water Lens test kit utilizes several independent detection motifs in a 96-well plate format. Each 8-well strip (12 strips to a plate) is filled with a different assay, each of which contains a colorimetric dye (and other constituents) sensitive to the presence of the component being measured. The assays are then freeze-dried, which provides for a long shelf life (even in harsh environments) and rapid rehydration upon introduction of the sample. The tests have all been carefully formulated to be compatible with high TDS and TSS produced waters found in industries such as oil and gas, mining, industrial, waste water, and agriculture.
The Water Lens test kit operates on the principle of colorimetric absorption by photosensitive dyes. When the dyes bind to their respective analytes, the photometric spectrum of the dyes change. These changes are read by monitoring the absorbance of light at specific wavelengths as light passes through the sample. The absorbance characteristics are read by a colorimeter, and the data generated is used to calculate the concentration of the particular analyte in the sample using proprietary Water Lens software.
