API Food Poison Detection: Cyanides, Azides & Heavy Metals
Ask For Quote

The JDK detection card utilizes TABS technology to detect levels of poisons which are Immediately Dangerous to Health and Life, (IDHL). The JDK detection cards were designed to detect heavy metals including Lead, Mercury, Cadmium and Thallium, as well as Cyanides, Azides, Sulfides and Chromates. Liquid foods and drinks can be analyzed directly. Solid foods have to be mixed with twice its volume of clean water, stirred vigorously, and the liquid analyzed. About 2-7 droplet of liquid sample or food extract are applied in three locations on the JDK detection card. The presence of poison is indicated by a clear color change which may be compared with reference colors pre-printed on the card. The color changes in 1 second to 5 minutes depending on the viscosity of the food sample. The analysis is typically completed in 2-10 seconds. The detector was designed to analyze FOOD samples. Therefore, the sample has to be in the pH range of foods. Please do NOT attempt to analyze samples which are in a strong acidic, basic or salty solution. PURE materials have to be diluted by a factor of at least 200 before analysis.

This detector can be used to detect heavy metals including Lead, Mercury, Cadmium and Thallium, as well as Cyanides, Azides, Sulfides and Chromates in food before consumption and in food residues. The US DOD funded a portion of the development work and independent validation tests.

Note: This detector has a significantly lower price than the CA and HM detectors but it does not have the QAD tabs used to validate its performance. Except for during shipment, the detectors have to be stored refrigerated and used within six months.
