Page 6: Background Information
BACKGROUND INFORMATION Introduction to Colorimetric Measurement. Palintest tests are based on measuring the intensity of colours produced by Palintest reagents and using Palintest photometers to measure that intensity of colour. This is colorimetry and can be defined as any technique used to evaluate an unknown colour in reference to known colours. - Page 7 In this case, a green filter gives the greatest sensitivity as a pinkish-red solution absorbs mostly green light. Palintest photometers calculate and then display the test results directly in milligrams per litre (mg/l) of the test factor, by comparing the amount of absorbed light to the calibration data programmed into the instrument.

Page 8: Blanks And Samples
Blanks and Samples Palintest photometers use a BLANK tube to set the instrument to blank and a SAMPLE tube to take the reading. A BLANK tube is a test tube filled with untreated water sample. A SAMPLE tube is a test tube containing the sample to which reagents have been added in accordance with the test procedure described. -
Page 9: Care And Maintenance
Care and Maintenance The handling of photometer tubes is important to ensure continuing accuracy. Scratches, finger-prints and water droplets on the tube or inside the light chamber can cause inaccurate results. It is imperative that the tubes and light chamber are clean and dry. The glassware must be clean and defect-free. -
