Section 4 Operation

4.1 Analyse Ammonium-Nitrogen/Ammonium with

HACH-LANGE Cuvette Tests

DANGER Handling chemical samples, standards and reagents can be dangerous. Users of this product are advised to familiarize themselves with safety procedures and the correct use of chemicals, and to carefully read all relevant material safety data sheets.

To analyse Ammonium or Ammonium-Nitrogen follow the working procedure enclosed in the according Cuvette Test LCK 303, LCK 304 or LCK 305.

4.2 Quality assurance

The measurement results must be subjected to plausibility checks (dilute and/or spike the sample).

Regular checks with corresponding standard solutions (see Section 5 Replacement

Parts and Accessories on page 19) ensure that your measurement system is

functioning properly and is being correctly operated.

4.3 Evaluate HACH-LANGE Ammonium-Nitrogen/

Ammonium Cuvette Tests

Note: Make sure that the instrument is programmed with the corresponding calibration data, see 3.4 Check entered data on page 14.

1. Fill DI water into an empty cuvette (LCW 919) up to the lower edge of the barcode label.

2. Close the cuvette with the rubber stopper. This is the blank cuvette.

3. Thoroughly clean the outside of the cuvette.

4. Press POWER to switch on the instrument.

5. Make sure that the correct measuring range is selected!

Otherwise press MENU. "SEL" is displayed. A flashing arrow indicates the current measuring range (1 or 2). Press GREEN key to select measuring range. Press MENU to get back to the measuring mode.

6. Insert the blank cuvette into the cell holder equipped with the cuvette adapter 1cm.

Note: Make sure that the cuvette adapter is positioned correctly.

7. Place the instrument cap with the HACH-LANGE label over the cell holder to cover the cuvette.

8. Press BLUE key. "0.00" (LCK 303/305) or "0.000“ (LCK 304) is displayed.

9. Remove the instrument cap and insert the sample cuvette.

10. Place the instrument cap over the cell holder to cover the cuvette.

11. Press GREEN key.

Operation

12. The result is displayed in mg/l Ammonium-Nitrogen/Ammonium.

Note: In case the Ammonium-Nitrogen/Ammonium concentration is out of the selected measuring range the value for the lowest or highest concentration is displayed and flashes. Repeat the test using the appropriate LCK Cuvette Test measuring range or dilute your sample.

Note: A new blank measurement should be performed prior to each individual test series.
