Section 6 Operation
DANGER
Chemical exposure hazard. Obey laboratory safety
procedures and wear all of the personal protective equipment
appropriate to the chemicals that are handled. Refer to the
current safety data sheets (MSDS/SDS) for safety protocols.
6.1 Routine operation
CAUTION
Burn Hazard. Do not put a finger in an opening in the heating
block. Close the protective cover before increasing the
temperature of the heating block, and always keep the
protective cover closed during operation.
CAUTION
Burn Hazard. Sample cells are hot. Wear thermal insulating
material (e.g., gloves or finger cots). Do not remove a sample
cell that is greater than 80 °C. Do not put a sample cell that is
greater than 80 °C in a colorimeter.
CAUTION
Chemical Hazard. If a sample cell breaks, do not let the liquid
touch skin. Use a fume hood as necessary to remove
chemical fumes.
CAUTION
Chemical exposure hazard. Dispose of chemicals and wastes
in accordance with local, regional and national regulations.
NOTICE
To prevent sample cell and instrument damage, keep the openings in
the heating block dry. Dry the outside of sample cells fully.
NOTICE
To prevent instrument damage, immediately disconnect power if an
accidental spill occurs or a sample cell breaks, then clean the
instrument. Refer to Clean the instrument on page 10.
NOTICE
Do not cover the ventilation slits in the protective cover. The instrument
and sample cells may become too hot and decrease the accuracy of
measurement.
1. Prepare the test sample cells as specified in the analysis procedure.
2. Close the sample cells with the cap.
3. Dry the outside of the sample cells fully.
4. Turn the instrument on and open the protective cover. The last
temperature program(s) selected is shown on the display.
5. If using 16 mm tubes with a heating block with 20 mm openings, put
reducing adapters in the openings.
6. Select the correct temperature program (and digestion period if
applicable) using the keys, then push Start. Refer to Stored
programs on page 9. The temperature program is selected
independently for each heating block when there are two heating
blocks.
Note: To stop a program, push the key below the program two times.
7. When the heating block is at the selected temperature (two beeps
are heard), put the test sample cells in the correct heating block and
close the protective cover.
8. Push Start to start the program.
The time counts down to zero (0). When the digestion program is
completed, three beeps are heard and the heater turns off.
6.2 Stored programs
Table 3 gives descriptions of the stored temperature programs.
English 9
Table 3 Stored programs
Program Description
COD Increases the temperature of the sample cells to 150 °C for
120 minutes. In the cooling phase, four beeps are heard
when the sample cells are at 120 °C. Remove and carefully
invert the sample cells several times, before letting them
decrease in temperature in a rack.
TOC Increases the temperature of the sample cells to 105 °C for
120 minutes. The TOC temperature program can be used
for all Hach TOC sample cell tests.
100 °C Increases the temperature of the sample cells to 100 °C for
30, 60 or 120 minutes. For example, the “100 °C,
60 minutes” temperature program is used to:
• Digest samples using the Metals Prep Set
• Identify phosphate and chromium
• Digest heavy metals
105 °C Increases the temperature of the sample cells to 105 °C for
30, 60 or 120 minutes.
150 °C Increases the temperature of the sample cells to 150 °C for
30, 60 or 120 minutes.
165 °C Increases the temperature of the sample cells to 165 °C for
30, 60 or 120 minutes.
6.3 User programs
The DRB 200 has three temperature programs that are configured by
the user (PRG1–PRG3).
To configure a user temperature program:
1. Select a user temperature program using the keys.
2. Push Prog to enter programming mode.
3. Select a 4-character name for the program. Push the left key to
change the character. Push the right arrow key to move the cursor to
the next position. Push OK to save the change.
