1. Introduction

Nitrogen Sample Concentrator BCON-104 is mainly used for concentrating or preparing sample in batch. Such as drug screening, hormone analysis, liquid phase and mass spectrometry in the analysis of sample preparation. It works by blowing nitrogen, in the surface of sample which is being heated to accelerate evaporating and separating the solvent in the samples without oxygen.

1.1 Feathers

1. The heater causes the sample to be rapidly heated to the evaporation temperature, and at the same time, the gas is blown to the surface of the solution through the gas needle, which promotes the rapid evaporation of the solution and the concentration of the sample.

2. The height of the air chamber assembly is adjustable, and the standard air needle length is 150mm.

3. When the sample is concentrated, the liquid level position of the concentrated sample can be observed at any time.

4. Gas needle is controlled independently. Separately blow of each needle and flow regulating of each needle are available to avoid gas waste.

5. The entire equipment can be put into ventilation cabinet when the concentration sample in toxic solvents.

6. Built in overheat protection, automatic fault detection and fault beep alarm devices.

7. LED display immediate temperature and diminishing time. Operation is simple and convenient.

3.Preparations

This chapter introduces the instrument’s mechanical structure, keyboard and each key’s function and some preparations before power on. You should be familiar with this chapter before the instrument is first operated.

3.1 Structure Description

3.2 Instrument Installation

Assembly

3.3 Installation steps

1. Put the dry bath on the bench smoothly and solidly
2. Fully insert the column into a square hole of the column holder behind the host, then srew knob into the column mounts, and finally tighten the knob to secure the uprights

3. Screw fixed knob of the mobile seat into the threaded hole on the left side of the mobile seat, then hold knob of mobile seat and counterclockwise rotate the hand wheel adjustment. When reach the desired position, we can tighten the knob to fix mobile seat. Clockwise rotating the hand wheel adjustment, the mobile seat will decline (as shown in the picture).

Note: When move the seat, two hands must be used in conjunction with operating mobile seat fixed knob and hand wheel adjustment

4. Screw fixed knob of the gas chamber into the threaded hole on the left side of the movable block, then insert column of gas chamber into the corresponding hole of the front movable block. Fully inserted column of gas chamber, then tighten fixed knob. (as shown in the picture)

3.4 Gas Control Valve (optional purchasing auxiliary)



Pull out the gas pressure adjust knob, clockwise rotate the knob to increase pressure, anticlockwise rotate the knob to decrease pressure. Push back the knob to lock pressure.
Clockwise rotate the gas flow adjust knob to increase flow rate, anticlockwise rotate the knob to decrease flow rate till shut off it.

3.4 Installation of nitrogen flow rate adjusting valve

The composition of nitrogen flow rate adjusting valve.


As the above picture, connect the outlet of the nitrogen flow regulator valve with outlet port of the host with a short hose (about 1.5m). Connect the inlet of nitrogen flow regulator valve with outlet port of the host with a long hose (about 3m)

Note- Slowly open the valve of the nitrogen bottle to control the outlet pressure between 0.1MPa to 0.2MPa, and then open the valve adjusting knob to keep pressure value at 0.02MPa. According to the number of holes, we can adjust the pressure appropriately (usually between 0.02MPa and 0.05MPa optional).

4. Operation panel

Button instruction:

Decreasing button decrease the figure set

Increasing button decrease the figure set

START/STOP Run/stop button - Run when you press the button once after setting the temperature and the time. Stop when you press this button for 2s.

5. Operation Guide

5.1 Temperature and time set:

The LED will display “ ” as the chart when the Instrument powers on and the Instrument goes into the initial state with the sound of “du…”.
About 2s later, the figure 28.5 is the block’s current temperature; 00:35 in the time display is the last set time.

Press or of the “Temp” key and keep off at once. Now, the value in the temperature display is the former setting temperature. As shown in the left drawing, the last digital of the setting temperature is flickering. If you want to set the temperature to 55.5 °C , do as follows:

Keep pressing when it reach 55.5 °C, stop Pressing, it will auto save as 55.5 °C
Keep pressing the above keys for 2 seconds. We can modify the value fleetly. It is very convenient.

Press or of the “Time” key and keep off at once, the value in the time display is the former setting time. Shown in the left drawing is 00:35 (35minutes). At same time, the last digital is flickering.

If you want to change the time to 01:20, do as follows: Keep pressing , when it reach 01:20, stop Pressing, it will auto save as 01:20.

Note- If the time setting is 00:00, meaning the time of operation is forever, the Instrument run constantly in setting temperature.

5.2 Operation and stop:

Meanwhile, there is current temperature in the temperature display, and the radix point is flickering regularly during the rise process.
When the temperature stops to rise, the flickering also stops. in the time display begins flickering, then the counting down starts.

When the timing is stopped, the operation is also stopped.
The buzzer alarms. Current temperature in the temperature display and in time display mean “over”, the
complishment of the operation.

After accomplishment of the operation, the instrument is in standby mode waiting for new declaration. Then pressing the keys near Temp or “Time” can reset the temperature or the time. Pressing START/STOP, it will operate according to last setting.

Press START/STOP for 2s during the operation, it will stop running. Press this button again, operation will continue.

5.3 Temperature error adjustment

The temperature of the Instrument has been adjusted before it is sold out. In case there is deviation between the actual temperature and the displayed temperature, you can do as follow for temperature calibration.

NOTICE:

1. The instrument has 2 calibration temperature points to ensure the veracity.
It is linearly adjusted on 40°C and 100°C. The temperature accuracy will be within
±0.5°C after temperature calibration.
Both the environmental and the block temperature should be lower than 35° C when calibration.

5.4 Adjustment Methods:

a- Power on the instrument, it enters into waiting interface. Make sure the current temperature in display is below 35°C. If the temperature is higher than 35°C, please wait until it down below 35°C.

b- Inject olefin oil into one of block well, and then put a thermometer into this well (the precision of the thermometer should be 0.1°C and the temperature ball should be absolutely immerged into the olefin oil in the block well). Adiabatic material is needed on the block to separate it from the circumstance. (refer to below Figure A)



Figure A

NOTICE : To ensure the calibration precision, read the actual temperature value after the temperature reaches calibration points for at least 20 minutes.

Press and simultaneously to enter the temperature calibration interface as the right chart. LED display in the time display, the temperature display the current temperature and the program auto control the temperature to 40°C.

When the temperature reaches 40°C, the decimal digit begins to flicker. Wait for at least 20 minutes, after 20 minutes of constant temperature, read the measured temperature of the thermometer.

Notice- In order to ensure the temperature calibration accuracy, it is recommended that users read the temperature after 20 minutes of constant temperature
Measured temperature.

If the thermometer reads 39.6°C, the actual temperature of thermometer is 39.6C
press and of temperature to amend the temperature value to 39.6, Press “Start/Stop” to confirm.

Then the instrument automatically heats up to 100°C, and waits for the temperature calibration value to be input after a constant temperature of 100°C. It is also required to read the measured temperature of the thermometer after 20 minutes of constant temperature.

Notice! In order to ensure the temperature calibration accuracy, it is recommended that users read the temperature after 20 minutes of constant temperature
Measured temperature

If the actual temperature of thermometer is 101.5°C, press or or of temperature to amend the temperature value to 101.5, Press “Start/Stop” to confirm.

After temperature have been adjusted, press and simultaneously to exit the temperature calibration and return to waiting interface.

Notice:
After temperature calibration, the temperature display is the same as the practical temperature of block.
