Page 5: General Information
Poison Control Center listed in the front of the phone book. Be prepared to supply the name and four-digit LaMotte code number found on the container label or at the top of the MSDS. LaMotte reagents are registered with a computerized poison control information system available to all local poison control centers. -
Page 6: Limited Warranty
(2) years from original purchase date. In the event that a defect is found during the warranty time frame, LaMotte Company agrees that it will be repaired or replaced without charge except for the transporation costs. This guarantee does not cover batteries. -
Page 7: Statistical And Technical Definitions
STATISTICAL AND TECHNICAL DEFINITIONS RELATED TO PRODUCT SPECIFICATIONS Method Detection Limit (MDL): “The method detection limit (MDL) is defined as the minimum concentration of a substance that can be measured and reported with 99% confidence that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix containing the analyte.”... -
Page 8: Contents And Accessories
Sensitivity: Sensitivity is the resolution based on how this term is used in LaMotte catalogs. This term is not listed in any of the references. Sometimes it is used for detection limit. It is a confusing term and should be avoided. -

Page 10: Chemical Testing
This type of sampling requires more sophisticated sampling equipment. For dissolved oxygen studies, or for tests requiring small sample sizes, a Water Sampler (LaMotte Code 1060) will serve as a subsurface or in-depth sampler. SMART2 COLORIMETER 1.07... -
Page 11: Filtration
To test for total constituents, organically bound and suspended or colloidal materials, a rigorous high temperature acid digestion is necessary. **LaMotte offers a filtering apparatus: syringe assembly (Code 1050) and membrane filters, 0.45 micron, (Code 1103). SMART2 COLORIMETER 1.07... -
Page 12: An Introduction To Colorimetric Analysis
AN INTRODUCTION TO COLORIMETRIC ANALYSIS Most test substances in water are colorless and undetectable to the human eye. To test for their presence we must find a way to “see” them. The SMART2 Colorimeter can be used to measure any test substance that is itself colored or can be reacted to produce a color. -
Page 13: Reagent Blank
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 14: Calibration
CALIBRATION CURVES The Smart2 Colorimeter contains tests for the LaMotte reagent systems (see Page 49). The first step in using a non-LaMotte reagent system with your Smart2 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 Smart2 Colorimeter. - Page 15 3. Use the unreacted 0 ppm standard to standardize the colorimeter by using it to scan blank. 4. Following the individual reagent system instructions, react each standard solution beginning with 0 ppm. Continue with standards in increasing concentration. Record the reading and the standard solution concentration on a chart.
-
Page 16: Standard Additions
PREPARING DILUTE STANDARD SOLUTIONS Standard solutions should be prepared to create a calibration curve. Standard solutions can be prepared by diluting a known concentrated standard by specified amounts. A chart or computer spreadsheet can be created to determine the proper dilutions. Use volumetric flasks and volumetric pipets for all dilutions. -
Page 17: Sample Dilution Techniques & Volumetric Measurements
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. -
Page 18: Interferences
LaMotte reagent systems are designed to minimize most common interferences. Each individual test instruction discusses interferences unique to that test. Be aware of possible interferences in the water being tested. The reagent systems also contain buffers to adjust the water sample to the ideal pH for the reaction. -
Page 19: Operation Of The Smart2 Colorimeter
The test library consists of 100 LaMotte tests (not all 100 may be available at present) and 10 “User Tests”. The LaMotte tests are precalibrated for LaMotte reagent systems. -

Page 23: General Operating Procedures
GENERAL OPERATING PROCEDURES The operation of the SMART2 Colorimeter is controlled by a microprocessor. The microprocessor is programmed with menu driven software. A menu is a list of choices. This allows a selection of various tasks for the colorimeter to perform, such as, scan blank, scan sample, and edit test sequences. -
Page 24: The Display & The Menus
THE DISPLAY & THE MENUS The display allows menu selections to be viewed and chosen. These choices instruct the colorimeter to perform specific tasks. The menus are viewed in the display using two general formats which are followed from one menu to the next. - Page 25 The second general format of the display takes advantage of the graphics capabilities of the display. The top line of the display is still a title line. The middle two lines of the display are used to display important messages, results or graphics in a large, easy to read format.

Page 45: Selecting The Numerical Format Of The Result
SELECTING THE NUMERICAL FORMAT OF THE RESULT To input tests with very different ranges, the number of decimal places displayed for a result can be selected. A test which ranges from 20 to 1000 ppm should not be displayed with three decimal places. A test with a range from 0.010 to 0.500 needs three decimal places (the microprocessor will always calculate the concentration to many more significant figures than will be displayed). -
