Abstract

Apparatus for detecting the presence of foreign substances in a beverage. The apparatus for detecting the presence of Gamma-hydroxybutyrate or other drugs in a beverage comprises apparatus wherein cobalt nitrate, oxammonium chloride/ferric chloride, oxammonium sulphate/ferric chloride, 5% ferric chloride, saturated potassium dichromate, toluene/cobalt thiocyanate, chromium (IV) oxide/sulphuric acid carbodiimide salts in combination with oxammonium salts and ferric chloride, or lacmoid is supported on a substrate. The apparatus for detecting the presence of ketamines or other drugs in a beverage comprises apparatus wherein modified-Dragendorff Reagent is supported on a substrate.

Claims (24)

1. An apparatus for detecting the presence of ketamines or other drugs in a beverage, the apparatus comprising:

a substrate and

a modified-Dragendorff Reagent comprising sodium bisulphate;

wherein the modified-Dragendorff Reagent comprising sodium bisulphate is supported on the substrate.

2. The apparatus according to claim 1 , wherein the substrate is selected from absorbent paper, filter paper, cellulose sheet, cellulose film or cardboard.

3. A test kit comprising the apparatus of claim 1 .

4. The test kit according to claim 3 additionally comprising a test for other drugs.

5. The test kit of claim 3 additionally comprising instructions for use.

6. The apparatus according to claim 1 , wherein the modified-Dragendorff Reagent comprises potassium and bismuth.

7. The apparatus according to claim 1 , wherein the modified-Dragendorff Reagent comprises potassium, bismuth, iodine, and sodium bisulphate.

8. The apparatus according to claim 1 , wherein the modified-Dragendorff Reagent is formed by mixing potassium iodide, sodium bisulphate, and bismuth nitrate.

9. The apparatus according to claim 1 , wherein the modified-Dragendorff Reagent is formed by:

mixing potassium iodide and sodium bisulphate to form solution A;

mixing bismuth nitrate, methylated spirits, and hydrogen chloride to form solution B; and

mixing solution A and solution B to form the modified-Dragendorff Reagent.

10. The apparatus according to claim 1 , wherein the sodium bisulphate is present at a concentration sufficient to reduce precipitation of bismuth from the modified-Dragendorff Reagent as compared to a Dragendorff Reagent not containing sodium bisulphate.

11. The apparatus according to claim 1 , wherein the modified-Dragendorff Reagent further comprises tartaric acid, oxalic acid, or citric acid.

12. The apparatus according to claim 1 , wherein the modified-Dragendorff Reagent is dry on the substrate prior to contact with a beverage.

13. The apparatus according to claim 1 , wherein the apparatus is formed by contacting the substrate and aqueous modified-Dragendorff Reagent and subsequently drying the substrate and the modified-Dragendorff Reagent.

14. The apparatus according to claim 1 , wherein an orange, pink, orange/pink, or orange/red coloration is formed after contact of the apparatus and a sample containing ketamine.

15. The apparatus according to claim 1 , wherein an orange/red coloration is formed after contact of the apparatus and a sample containing a secondary amine compound.

16. The apparatus according to claim 1 , wherein an orange/red coloration is formed after contact of the apparatus and a sample containing benzodiazepine.

17. The apparatus according to claim 1 , wherein a colorimetric indicator appears in less than 10 seconds after contact of the apparatus and a sample containing ketamine.

18. The kit according to claim 4 , wherein the test kit comprises a test for benzodiazepine, amphetamines, cocaine, barbiturates, opiates, tricyclic antidepressants, acetaminophen, propoxyphene, or phencyclidine.
