Page 6: Introduction
INTRODUCTION TURBIDITY What is Turbidity? Turbidity is an aggregate property of the solution, water in most cases. Turbidity is not specific to the types of particles in the water. They could be suspended or colloidal matter and they can be inorganic, organic or biological. At high concentrations turbidity is perceived as cloudiness or haze or an absence of clarity in the water. -
Page 7: How Is Turbidity Measured
860 nm and a spectral bandwidth less than or equal to 60 nm. The units of measurement for the ISO method are formazin nephelometric units (FNU). The 2020e meets the EPA specification and the 2020i meets the ISO specification. The nephelometric method is most useful for low turbidity. -
Page 8: Options And Set Up
All dilutions are based on a final volume of 10 mL so several dilutions will require small volumes of the water sample. Graduated pipets should be used for all dilutions. If volumetric glassware is not available, dilutions can be made with the colorimeter tube. - Page 9 2. Scroll down and then press *IOK M a i n M e n u to select Options.

Page 11: Averaging
The Japan Standard calibration mode should be used only with Japanese Polystyrene Standards (0–100 NTU). Note: StablCal ® standards below 50 NTU should not be used to calibrate the 2020. The diluent has a different refractive index than traditional formazin standards and will affect the results. -

Page 22: Dilution Procedures
Dilution Procedures If a sample is encountered that is more than 4000 NTU, a careful dilution with 0 NTU or very low turbidity water will bring the sample into an acceptable range. However, there is no guarantee that halving the concentration will exactly halve the NTU value. Particulates often react in an unpredictable manner when diluted. - Page 23 2. Pour approximately 50 mL of deionized water into the barrel of the syringe. Insert the plunger. Exert pressure on the plunger to slowly force the water through the filter. Collect water in the clean storage container. Rinse walls of the container then discard this rinse water. 3.

Page 24: Turbidity Standards
The concentration of the calibration standard should be similar to the expected concentration of samples that will be tested. The following standards are available from LaMotte Company: 1480 0 NTU Standard, 60 mL (EPA and ISO) - Page 25 4. Fill the tube to the fill line with the blank. Pour the blank down the inside of the tube to avoid creating bubbles. Cap the tube. 5. Dry the tube with a lint-free cloth. Put on a dry positioning ring. Cap the tube.
- Page 26 8. Rinse a clean tube (0290), or the same tube, three times with the standard. Avoid spilling standard on the outside of the tube. IMPORTANT: While the tube is inverted, wipe the lip of the tube to remove droplets of liquid that may be present.

Page 36: Tubes
Tubes The 2020 uses one type of tube (Code 0290) for the turbidity test. There is no need for a special turbidity tube. The handling of the tubes is of utmost importance. Tubes must be clean and free from lint, fingerprints, dried spills and significant scratches, especially the central zone between the bottom and the sample line. -
