Good Ideas:

• When assembling the sample cell, always work over a lab counter
• Never leave the desiccator open to the atmosphere
• Use 2-3 drops of sample on the NaCl windows
• Never over tighten the retaining nuts on the sample cell
• Plan on 15-20 minutes for a complete scan.
• Clean the sample cell when you are finished.
• Cap the pen when you are done..don't let it dry out!
