First Standard: 100 ppm• Add 10-ml of solvent tothe 10-ml graduatedcylinder

First Standard: 100 ppm• Add 10-ml of solvent tothe 10-ml graduatedcylinder• Using the syringe add10 microliters of oil to 10-ml of solvent in thegraduated cylinder

First Standard: 100 ppm• Add 10-ml of solvent tothe 10-ml graduatedcylinder• Using the syringe add10 microliters of oil to 10-ml of solvent in thegraduated cylinder• Pour this standard intoa vial labeled “100 ppm”

First Standard: 100 ppm• Add 10-ml of solvent tothe 10-ml graduatedcylinder• Using the syringe add10 microliters of oil to 10-ml of solvent in thegraduated cylinder• Pour this standard intoa vial labeled “100 ppm”•Shake to mix

Second Standard: 50 ppm• Pour 5-ml of the 100 ppm standard back into the10-ml graduated cylinder

Second Standard: 50 ppm• Pour 5-ml of the 100 ppm standard back into the10-ml graduated cylinder• Fill the cylinder to 10-ml with clean solvent

Second Standard: 50 ppm• Pour 5-ml of the 100 ppm standard back into the10-ml graduated cylinder• Fill the cylinder to 10-ml with clean solvent• This will cut the 100 ppm standard in half to be 50ppm

Second Standard: 50 ppm• Pour 5-ml of the 100 ppm standard back into the10-ml graduated cylinder• Fill the cylinder to 10-ml with clean solvent• This will cut the 100 ppm standard in half to be 50ppm• Pour this standard into a vial labeled “50 ppm”

Second Standard: 50 ppm• Pour 5-ml of the 100 ppm standard back into the10-ml graduated cylinder• Fill the cylinder to 10-ml with clean solvent• This will cut the 100 ppm standard in half to be 50ppm• Pour this standard into a vial labeled “50 ppm”• Shake to mix

Third Standard: 25 ppm• Pour 5-ml of the 50 ppm standard back into the10-ml graduated cylinder• Fill the cylinder to 10-ml with clean solvent

Third Standard: 25 ppm• Pour 5-ml of the 50 ppm standard back into the10-ml graduated cylinder• Fill the cylinder to 10-ml with clean solvent• This will cut the 50 ppm standard in half to be 25ppm

Third Standard: 25 ppm• Pour 5-ml of the 50 ppm standard back into the10-ml graduated cylinder• Fill the cylinder to 10-ml with clean solvent• This will cut the 50 ppm standard in half to be 25ppm• Pour this standard into a vial labeled “25 ppm”

Calibration to Prepared Standards• Make sure InfraCal has been on for1 hour

Calibration to Prepared Standards• Make sure InfraCal has been on for1 hour• Make sure sample plate is clean

Zeroing• Fill the cuvette with clean solvent and place inthe sample stage with the frosted side facingfront.

Zeroing• Press and hold the ZERO button until thedisplay reads bAL.bALRUNCALZERORecall

Zeroing• A multiplier value to 3 decimal places will bedisplayed when zero is established. The actualvalue is only of interest when reportingproblems to the factory1.267RUNCALZERORecall

Zeroing• Press RUN. . The display should read 00 + 02If not, repeat the zero process00RUNCALZERORecall

Calibration to Prepared Standards• Run each standard at least 3 times in theInfraCal

Calibration to Prepared Standards• Run each standard at least 3 times in theInfraCal• Average results for each standard

Calibration to Prepared Standards• Run each standard at least 3 times in theInfraCal• Average results for each standard• Enter averaged results under the “A” in themanual on page 13 or 14 and thecorresponding calibration value in the Ccolumn
