WARNING
Burn hazard. The digestion block gets extremely hot. Do not touch.
The BD40HT is a high-temperature block digestion system. A color touchscreen controller gives
power to the digestion block (Figure 1). The controller holds 12 test methods. The test methods
control test times and temperatures and can be modified as necessary.
The digestion block holds 40 digestion tubes (Figure 2). Samples can be heated to 450 °C.

Complete a digestion method
WARNING
Burn hazard. The digestion block gets extremely hot. Do not touch.
WARNING
Gas inhalation hazard. Operate the instrument in a fume hood to prevent exposure to hazardous gas.
N O T I C E
Refer to the written method for the specific details of each test.
1. Make sure that the rack and digestion tubes are not in the graphite block.
2. At the controller, select the Menu tab.
3. Push the name of the method to select it. The Run screen shows.
4. On the Run screen, push START. The digestion block will start to get hot.
Note: Make sure that the dongle is installed in the COM 2 connector on the controller (Figure 1 on page 6).
5. Prepare the sample as shown in the written method.
6. When the sample is added to the digestion tubes, put the tubes in the rack.
7. When the digestion block is at the temperature set point, carefully set the rack with the filled
digestion tubes in the graphite block.
8. When the reaction time is complete, carefully move the rack and digestion tubes to the position
shown in Figure 8. Refer to the written method for cool-down times.
Figure 8 Move the digestion tubes
Program a new method
1. On the Menu tab, push NEW METHOD. The Edit tab opens.
12 English

2. On the Edit tab, push NEW METHOD.
3. Use the keyboard to enter the name of the method. Push ACCEPT.
4. On the Edit tab, push Step 1.
5. At the bottom of the Edit tab, push Other to select glass digestion tubes.
6. Refer to the written method instructions to find the necessary information.
Option Description
Time TO Temperature Range: 0 to 999 minutes. The time that the digestion block will use to get to the
temperature set point. Refer to Find the "Time to Temperature" value on page 13.
Note: Enter a value of "1" to get to the temperature set point as fast as possible.
Time AT Temperature Range: 0 to 999 minutes. The amount of time for the method to stay at the Step
1 set point.
Setpoint Temperature The temperature is defined by the written method.
7. Repeat steps 5 and 6 for methods with additional temperature reaction periods.
Find the "Time to Temperature" value
There are two types of temperature change. The first is a temperature change from room
temperature to an initial set point (Example 1). This is usually a look-up value.
The second temperature change is for methods that have multiple temperature set points. In this
scenario, the block temperature will be above room temperature when the temperature increase is
started (Example 2). This value must be calculated.
Note: Enter "0" to keep the controller on the edit screen or disregard Step 2 or Step 3.
Example 1: Find the time to temperature value from room temperature to 250 °C. Refer to Figure 9.
Find where the temperature rate line crosses the 250 °C line. The minimum time to temperature from
room temperature to 250 °C is about 20 minutes.
Example 2: Increase the temperature from 250 °C to 400 °C.
1. To calculate the temperature change, subtract the first temperature from the second temperature.
The temperature change is:
400 – 250 = 150 °C.
2. Refer to Table 3. To find the rate of temperature increase, use the row for a temperature change
of 25–200. Read the value in the column for a set point of 350+. The rate of change is:
3 °C/min
3. Use the equation Temperature change ÷ Rate of change = Time to Temperature. The time to
temperature for the second set point is:
150 °C ÷ 3 °C/min = 50 minutes.

Calibrate the digestion block temperature
Temperature calibration is not necessary for normal operation. However, some methods may require
temperature calibration.
Note: Use the reference data table, available at www.lachatinstruments.com, to find the measured reference
temperature.
Items to collect:
• Ohmmeter (user-supplied)
• Temperature connection cable (supplied with the digestion block)
1. Connect the temperature connection cable to the digestion block. Refer to Figure 2 on page 7.
2. On the ohmmeter, connect the blue and white wires to the resistance probe.
Note: The bare wire is not connected.
3. On the Utilities tab, push TempPROBE.
4. In the TempPROBE column, enter the temperature of the first calibration point.
5. Push START.
6. The actual temperature shows in the temperature display above the keypad. When the
temperature is stable at the first calibration point, measure the resistance at the block.
7. Refer to the reference data table. Find the temperature value that corresponds to the measured
resistance. Enter that temperature value in the Reference column.
8. Push the temperature display above the keypad. The TempPROBE column will now show the
same temperature as the temperature display.
9. Repeat steps 4 through 7 for each calibration point.
10. Push ACCEPT to keep the calibrated temperature data. Push DECLINE to remove the data and
start again.
English 15

Calibrate the touchscreen
The touchscreen is calibrated at the factory. If the touchscreen response becomes slow or is out of
alignment, use this procedure to calibrate the touchscreen.
1. On the Utilities tab, push TouchScreen.
2. Push each of the three prompts as they show.
3. A second set of prompts shows. Push each prompt in sequence. After all prompts are selected,
the screen shows the Utilities tab.
Note: The screen will return to the Utilities tab without a change if no prompts are pushed.

English 17

Fuse replacement
Fuses are not user-serviceable items. The need for fuse replacement in controllers indicates severe
technical failure and is therefore considered to be a service activity. If a blown fuse is suspected,
contact Technical Support.
Troubleshooting
Problems with the digestion block cause an alarm to sound and a safety message to show on the
controller display. The controller will no longer apply heat to the digestion block and it will start to
cool. Refer to Table 5.
After the problem is resolved:
• Push CONTINUE to clear the message and let it occur again if necessary.
• Push SUSPEND to disable the message until the system is powered off.
