[. . . ] HI 93749-01 Reagents for 100 tests HI 93749-03 Reagents for 300 tests For other accessories see page 73. MEASUREMENT PROCEDURE · Select the Chromium VI LR method using the procedure described in the Method Selection section (see page 12). 10 mL · Press the or to go back to the measurement screen. · Fill the cuvette up to the mark with 10 mL of unreacted sample and replace the cap. · Place the cuvette into the holder and close the lid. The meter will show "-0. 0-" when the meter is zeroed and ready for measurement. INTERFERENCES Interference may be caused by: Vanadium above 1 ppm. However, waiting 10 minutes before reading, the interference is removed Iron above 1 ppm Mercurous and mercuric ions cause slight inhibition of the reaction. · Remove the cuvette and add the content of one packet of HI 93749-0 reagent. Replace the cap and shake vigorously for about 10 seconds. Chromium VI HR 28 29 Chromium VI LR · Reinsert the cuvette into the instrument. · Press TIMER and the display will show the countdown prior to the measurement or, alternatively, wait for 6 minutes and press READ. When the timer ends the meter will perform the reading. The instrument displays concentration in µg/L of chromium VI. COLOR OF WATER SPECIFICATIONS Range Resolution Accuracy Typical EMC Deviation Light Source Method 0 to 500 PCU (Platinum Cobalt Units) 1 PCU ±10 PCU ±5% of reading ± 1 PCU Tungsten lamp with narrow band interference filter @ 420 nm Adaptation of the Standard Methods for the Examination of Water and Wastewater, 18th edition, Colorimetric Platinum Cobalt method. REQUIRED ACCESSORIES 0. 45 µm membrane for true color measurement. For other accessories see page 73. MEASUREMENT PROCEDURE · Press the or to access the second level of functions. · Press the Chem Frm functional key to convert the result in µg/L of Chromate (CrO42-) and Dichromate (Cr2O72-). · Select the Color of Water method using the procedure described in the Method Selection section (see page 12). 10 mL · Fill one cuvette up to the mark with deionized water and replace the cap. · Place the blank (# 1) into the holder and close the lid. #1 #1 · Press the or to go back to the measurement screen. The meter will show "-0. 0-" when the meter is zeroed and ready for measurement. INTERFERENCES Interference may be caused by: Vanadium above 1 ppm. However, waiting 10 minutes before reading, the interference is removed. Iron above 1 ppm Mercurous and mercuric ions cause slight inhibition of the reaction. · Remove the blank. Chromium VI LR 30 31 Color of Water · Fill the second cuvette up to the mark with unfiltered sample and replace the cap. · Filter 10 mL of sample through a filter with a 0. 45 µm membrane into the third cuvette, up to the 10 mL mark and replace the cap. This is the true color. 10 mL COPPER HIGH RANGE SPECIFICATIONS Range Resolution Accuracy Typical EMC Deviation Light Source Method 0. 00 to 5. 00 mg/L 0. 01 mg/L ±0. 02 mg/L ±4% of reading ±0. 01 mg/L Tungsten lamp with narrow band interference filter @ 575 nm Adaptation of the EPA method. The reaction between copper and the bicinchoninate reagent causes a purple tint in the sample. Description Bicinchoninate Quantity 1 packet #2 #3 · Insert the apparent color cuvette (# 2) into the instrument and close the lid. · Press READ to start the reading. · The meter displays the value of apparent color in PCU. #2 REQUIRED REAGENTS Code HI 93702-0 REAGENT SETS HI 93702-01 Reagents for 100 tests HI 93702-03 Reagents for 300 tests For other accessories see page 73. MEASUREMENT PROCEDURE · Remove the cuvette, insert the true color cuvette (# 3) into the instrument and ensure that the notch on the cap is positioned securely into the groove. #3 · Select the Copper HR method using the procedure described in the Method Selection section (see page 12). · Fill the cuvette with 10 mL of unreacted sample (up to the mark) and replace the cap.
