| Application examples: | Grape juice, wine, beer, fruit juices, soft drinks, tea, dairy products (e.g. cheese), meat, processed meat, vegetable and fruit products, bakery products, paper, pharmaceuticals, cosmetics and other materials (e.g. biological cultures, samples, etc.). |
| Method recognition: | Methods based on this principle have been accepted by MEBAK, OIV, EU, ISO2963, AOAC and IFU22 (NOTE: If the enzyme oxaloacetate decarboxylase is present in the sample, some of the oxaloacetate product is converted to pyruvate. Therefore, to ensure citric acid is measured quantitatively, D-lactate dehydrogenase (D-LDH) is employed to efficiently convert any pyruvate produced into D-lactate and NAD+). |
The Citric Acid test kit is a flexible and simple method for the rapid and reliable measurement and analysis of citric acid (citrate) in foods, beverages and other materials.
Note for Content: The number of manual tests per kit can be doubled if all volumes are halved. This can be readily accommodated using the MegaQuantTM Wave Spectrophotometer (D-MQWAVE).

Attogene’s Cadmium Lateral Flow Kit can be used to detect Cadmium in water samples at 5 ppb in the field.
Format: 10 test cassettes
Run Time: 15-30 minutes
Cadmium contamination is a serious worldwide environmental problem. As it is difficult to detoxify by chemical or biological methods, gradual Cadmium accumulation in the nervous and cardiovascular systems of the human body can subsequently cause serious diseases. Long-term health consequences of drinking cadmium-contaminated food and water include numerous negative health effects. Attogene’s Cadmium Lateral Flow test gives results conforming of 5ppb or greater. Using the supplied pipette, simply fill the vial with your water sample, place the water into the sample port and wait 15-30 minutes.
