To test for their presence we must find a way to “see” them. The LaMotte colorimeter can be used to measure any test substance that is itself colored or can be reacted to produce a color. In fact a simple definition of colorimetry is “the measurement of color”... -

Handle the tubes carefully, making sure the bottom half of the tube is not handled. LaMotte Company makes every effort to provide high quality colorimeter tubes. However, wall thicknesses and diameter of tubes may still vary slightly. -
Page 12: Selecting An Appropriate Wavelength
CALIBRATION CURVES The SMART Colorimeter contains 42 precalibrated tests for the LaMotte reagent systems (see Page 49). The first step in using a non-LaMotte reagent system with your SMART Colorimeter is to create a calibration curve for the reagent system. To create a calibration curve, prepare standard solutions of the test factor and use the reagent system to test the standard solutions with the SMART Colorimeter. - Page 13 0, 10%, 30%, 50%, 70%, and 90% of the system’s maximum range. 2. Turn on the SMART Colorimeter. Select the appropriate %T/ABS wavelength from the %T/ABS Sequence in the TESTING MENU. Be sure to select the appropriate wavelength for the color produced by the reagent system.

Page 15: Preparing Dilute Standard Solutions
A common method to check the accuracy and precision of a test is by standard additions. In this method a sample is tested to determine the concentration of the test substance. A second sample is then “spiked” by the addition of a known quantity of the test substance. The second SMART COLORIMETER... -

0.3 + 0.5 = 0.8 ppm iron. (Note: any error due to the increased volume from the “spike” is negligible). LaMotte offers a line of calibration standards which can be used to generate calibration curves and perform standard additions. SAMPLE DILUTION TECHNIQUES &... -
Page 17: Interferences
10 mL of sample is diluted with three 10 mL volumes of demineralized water; the dilution factor is four. INTERFERENCES LaMotte reagents systems are designed to minimize most common interferences. Each individual test discusses interferences unique to that test. Be aware of possible interferences in the water being tested. - Page 18 The SMART Colorimeter checks for excessive stray light before scanning a blank or a sample. The SMART Colorimeter will not scan if it detects excessive stray light. If the message STRAY LIGHT!! appears in the display a blank or a sample has been scanned, cover the sample chamber and repeat the scan.

Page 19: Operation Of The Smart Colorimeter
The operation is controlled with the keypad through menu driven software in response to selections shown on the display. There are 42 LaMotte tests, 6 %T/Absorbance tests, and 25 User Tests stored in the colorimeter in a test library. The LaMotte tests are precalibrated for LaMotte reagent systems. -
