Automated measurement systems for water analysis
Background
QuoData is developing biochemical measurement systems for the detection of pharmaceutical and hormonal substances such as estrogens and antibiotics.

Automation of immunoassays
Any measurement system should be highly sensitive and the total cost per sample should be low. Methods such as GC‑MS(/MS) and LC‑MS(/MS) are sensitive and not too costly, when a multi method for many compounds can be established. Immunoassays in the manner of ELISA (Enzyme-linked Immunosorbent Assay) are an interesting alternative when there are only single compounds to be analysed or when single compounds cannot be taken into account within an existing multi method. Although detection limits of ELISAs are often in the ppt range, the quality of the results is highly affected by the matrix of samples, the conditions within the lab and the pipetting procedure.
Therefore, QuoData has developed the two analytical measurement systems ESTR‑A‑LISER and pharm‑a‑liser in cooperation with international partners. They enable low limits of detection and can be applied cost effectively for routine measurements.
Biosensor and Biological test system
In cooperation with the Institute of Plant Genetics and Crop Plant Research (IPK), QuoData is developing the EstraMonitor and the A‑YES KIT. Both are based on a yeast assay for the detection of estrogenic effects in waste water. Due to the robustness and the sensitivity of the yeast assay with regard to estrogenic effects, no sample preparation of the waste water is required.
