Heavy Metals Test 5-in-1 (Cadmium, Mercury, Lead, Copper, Zinc)

Des questions ?

• À quoi sert Heavy Metals Test 5-in-1 ?

  The 5-in-1 Heavy Metals Test contient a colorimetric réactif ideal for quickly et preliminarily confirming the presence of the most common heavy metals. Il sert à identifier avec certitude cadmium, mercury, lead, copper, et zinc, as well as to rule out other, less predictable, unwanted substances.

  The réactifs can indicate the PRESENCE of these metals, but not the QUANTITY. Mixtures can be reliably detected with réactifs only if one of the substances produces a stronger réaction de couleur. To identify all components with maximum precision, a set of different tests is required.

• Que contient le Heavy Metals Test 5-in-1?

  The Heavy Metals Test 5-in-1 comprend a two-part colorimetric réactif, a micropipette, a reaction tube, et instructions. The kit contient enough réactif for at least one test. The tightly sealed plastic container protects the réactif from light et moisture, ensuring a shelf life of at least 3 years after purchase.

• What can be tested with Heavy Metals Test 5-in-1?

  Only liquid samples can be tested – when testing solids, mix them with 4 ml of bottled water et filter out the solid particles. You can test herbs, powders, water, et other liquids (including breast milk, saliva, et first morning urine), food, kitchen utensils, et other objects, including toys et paints. If testing food, blend it et extract the juices. When testing fish, heat a raw échantillon in a microwave for 20 seconds to collect the juices.

  The échantillon’s pH should be close to 5.0; strongly acidic ou alkaline substances cannot be tested. The test works best at 5 PPM ou higher of heavy metals, but it may detect as little as 1 PPM ou less.

• Comment utiliser Heavy Metals Test 5-in-1?

  PREPARE THE REAGENT

  From the kit de test, take out the small vial with the dry réactif et the larger tube with the liquid réactif. Pour the contents of the small vial into the larger tube to combine both parts of the réactif, close the tube, et shake for 10 seconds.

  ADD THE SAMPLE

  Immediately add the échantillon to the prepared réactif solution: 4 ml of liquid, ou a solution made by mixing a dry échantillon with 4 ml of bottled water. 4 ml corresponds to one full volume of the included micropipette. The micropipette can be used several times to conveniently transfer the 4 ml. Filter ou carefully decant the solution to avoid adding any undissolved particles into the réactif tube. Close the tube et shake for 5 seconds to mix the échantillon with the réactif solution.

  OBSERVE FOR 60 MINUTES

  Place the small tube upright with the cap facing down, so the rounded end points up, et observe the changement de couleur reaction for 60 minutes. Both the initial colors right after adding the échantillon et the transitional et final colors are important. Take photos during the reaction.

  COMPAREZ LES RÉSULTATS

  Compare with the expected results provided in the instructions. Ignore any color changes after 60 minutes unless otherwise specified. Match the observed changement de couleur with the guide. The réactifs can indicate the PRESENCE, but not the QUANTITY. Mixtures can be reliably detected with réactifs only if one of the substances produces a stronger réaction de couleur. To identify all components with maximum precision, a set of different tests is required.

  Seal the used materials inside the plastic tube et dispose of them safely.

• Comment manipuler réactifs ?

  Réactifs contain toxic et/or corrosive chemicals, strong enough to burn skin et clothing. Keep out of the eyes et mouth. Tenez à l’écart des enfants et des animaux. Utilisez toujours dans un endroit bien ventilé. Portez des gants et des lunettes de protection. Never point towards the face etc. Si vous en renversez sur la peau ou les vêtements, lavez immédiatement à grande eau et au savon. Éliminez tout réactif non utilisé à l’eau courante, en aérant. Conservez les réactifs debout, à l’abri de la chaleur, dans un endroit frais et sombre.

  Les réactifs se dégradent avec le temps ou au contact de l’air, surtout s’ils sont exposés au soleil ou non réfrigérés. Si vous n’êtes pas sûr que le réactif fonctionne, testez-le avec un échantillon déjà confirmé.
