(Close the oven when you're done!)
Your sample may impart a light hue to the KBr mixture, but if it is highly colored, you should add more KBr to dilute it.
| Step 1. Get a mortar & pestle, pellet holder, 2 bolts and KBr out of the
oven. (Close the oven when you're done!) |
|
| Step 2. Measure out 3 spatula loads of KBr. This should be 100-200 mg. | |
| Step 3. Place one spatula-tip of sample in the mortar. You should never use more than a couple of milligrams. You do not need very much! | |
| Step 4. Grind the KBr to a very fine powder. Do this all quickly, as the
KBr will absorb water from the atmosphere, and this makes it difficult to press a good
pellet. Your sample may impart a light hue to the KBr mixture, but if it is highly colored, you should add more KBr to dilute it. |
|
| Step 5. Screw one bolt into the pellet holder. Place about 30-50 mg (a small spatula scoop) of the ground mixture into the cavity, and screw the second bolt in. | |
