DR/2400
Scope and Application:
* This test is semi-quantitative. Results are expressed as greater or less than the threshold value used.
Tips and Techniques
• Read the entire procedure before starting. Identify and make ready all the necessary reagents, cuvettes, and other apparatus
before beginning the analysis. A 1-cm square cell holder is required for this procedure.
• Timing is critical; follow instructions carefully.
• A consistent technique when mixing the cuvettes is critical to this test. The best results come from using the cuvette rack
and mixing as described in Using the 1-cm MicroCuvette Rack on page 5. Cuvettes can be mixed individually, but test results may
not be as consistent.
• Handle the cuvettes carefully. Scratches on the inside or outside may cause erroneous results. Carefully clean the outside of the
cuvettes with a clean absorbent cloth or tissue before placing them into the instrument.
• Antibody cuvettes and enzyme conjugate are made in matched lots. Do not mix reagent lots.
• To avoid damaging the Color Developing Solution, do not expose it to direct sunlight.
• The cuvette rack is designed to be inverted with the cuvettes in place. This is especially helpful when running many samples at
once; the cuvettes can remain in the rack and be processed together until they are read in the DR/2400 Spectrophotometer.
• Twenty Antibody Cuvettes are provided with each reagent set. One Antibody Cuvette will be used for each calibrator and each
sample. Cuvettes are not reusable.

For water
This method analyzes for Alachlor in water. Sample calibrators and reagents are
added to cuvettes coated with Alachlor-specific antibodies. The color that
develops is then measured and compared with the color measurements of the
calibrators. The test requires about 30 minutes for complete analysis. As many as
20 cuvettes (18 samples and 2 calibrators) can be run simultaneously.
Note: Hach Company recommends wearing protective nitrile gloves for this procedure.
