Chapter 1 GeneralIntroduction of Microwave Digestion System

Thank you for purchasing and using MWD-600 Closed Intelligent Microwave Digestion

System. We are very grateful for your trust, we will try our best to ensure that in coming days

your instrument running smoothly. In addition, if you need to form a complete set of

pretreatment equipment, welcome to choose and buy SPH-1 Sample Pretreatment Heating

Equipment which is tailored specifically for MWD series products.

Microwave digestion technology is a highly efficient sample preparation technology that

develops fast in recent years. It means,in a sealing container, using microwave heating principle,

under high temperature and high pressure to achieve the quickly and completely digestion of

inorganic or organic samples. Microwave digestion technology could well satisfy the

requirements of modern analytical instrument for sample preparation, with the advantages of

fast and uniform heating, less reagent dosage, low blank value, not easily polluted, energy

efficient, etc. Especially in the analysis of volatile element, it’s better to maintain sample

integrity and has a higher sample rate.

Microwave digestion system general consists of main body, temperature control system,

pressure control system, digestion tank, rotor system, exhaust system and software system.

MWD-600 Closed Intelligent Microwave Digestion System is a high-end microwave digestion

instrument. It has zero consumables design, all digestion tanks’ temperature and pressure

double control and display, self-recover sealing of high-pressure digestion function, sample

solution of the actual temperature and pressure monitoring and zero lag function. The MWD-600

is especially suitable for AAS, UV-VIS, ICP-AES, AFS, GFAA, XFS, ICP-MS, HPLC, etc. analysis; it

could accelerate the reaction, shorten processing time and improve the work efficiency. At

present the microwave digestion technology has been widely used in food, textile, geology,

metallurgy, plastics, coal oil, cosmetics, chemical, biological medicine, environment, wastewater

treatment, battery manufacturing, and other fields.

Тля тендера UA-2017-07-19-000683-а

(4) Temperature Control System

It monitors and controls the temperature changes in real time during the digestion

process.

(5) Digestion Tank

The digestion tank consists of a High Pressure Digestion Combined Tank and an Explosion-

proof Framework.

(6) High Pressure Digestion Combined Tank

The high pressure digestion combined tank combined by a sample digestion tank and a

protective outer tank. The sample digestion tank also known as the inner tank used to

contain the samples and acids .It provides a closed environment for the high temperature

and high pressure digesting, volume 100 ml. The protective outer tank also known as the

outer tank, it provides a protective environment for the high temperature and high

pressure digesting.

(7) Explosion-proof Framework

It provides a further security for the high temperature and high pressure digesting.

(8) Rotor System

It combined by a drive motor, a sample loading platform and an auxiliary platform. The

sample loading platform provides a space for loading the digestion tank. The auxiliary

platform provides a stable platform for monitoring the pressure. The drive motor keeps the

sample loading platform rotating uniformly and continuously on the auxiliary platform

toward the same direction.

(9) Exhaust System

It can blow out the spilling acids from the digestion tank in time and cool the digestion tank

when digestion completed.

(10)Software System

It ensures the instrument running intelligent and efficient.

2.2.2 Other Accessories

(1) Tank Holder

Users can place the inner tank into the tank holder.

(2) Unload Tool

Users cantake out the inner tank thattoo tight to remove after digestion with it.

(3) Pressure-plate

Users can calibrate instrument pressure signal in Instrument Calibration Interface with the

pressure-plate. There are two pressure-plates, the thick one is pressure-plate-6 that is used

to calibrate P6, and the thin one is pressure-plate-3 that is used to calibrate P3.

Chapter 3 Installation Conditions and Installation Guide

3.1 MWD-600 Installation Conditions

Please confirm the following conditions before installing the

instrument. 3.1.1 Working Power Supply

(1) Working Voltage: AC 220V, ±10%.

(2) Working Frequency: 50 or 60Hz, ±4%.

(3) Working Power: More than 2200W. The power should be over 2500W if there is any other

assist device.

(4) Earth Wire: Earth resistance should not be less than 100Ω, and should be in accordance

with the relevant regulations. The plug must be plugged into an outlet that is properly

installed and earthed.

3.1.2 Worktable

(1) The instrument must be installed on a horizontal and stabilization worktable over 640mm

length and over 630mm width which could bear over 75kg weight.

(2) The bigger worktable is required if assist device is also installed on the same worktable.

(3) For correct operation, the instrument must have sufficient air flow. Allow with 200mm of

space at the back and both sides of the instrument.

(4) The instrument is around 1055mm height when opening the upper cover, Please select

suitable worktable for the convenience of instrument operation.

(5) It is allowed to place the worktable next to the fume hood, but it is strictly prohibited to

put the instrument into the fume hood. Please avoid strong or continue vibration.

3.1.3 Installation Environment

The stand or fall of instrument working environment has a great influence for the

instrument performance and service life. Please confirm the following environment of the

installation place.

(1) Working environment temperature range: 5～40℃。

(2) Working environment humidity range: 45～85％。

(3) Storage environment temperature: -20～70℃。

(4) Indoor environment:

1) Make sure that there is no acidic or alkaline gas in room.

2) Make sure that there is no corrosive organic gas to etch the paint in room, especially for

gases such as benzene.

3) Make sure that there is concentrated exhaust device in room. Do not use the

instrument in corrosive gas environment and long time, that’s not conducive to the

instrument maintenance.

4) The external surface of instrument should be kept clean frequently.

(5) Sample Reagent

1) Please don’t place the corrosive solution such as sample reagents, acid and alkali

solution near the instrument.

2) It must be careful when taking the corrosive solution to avoid dripping or upset on the

surface of instrument or furnace chamber or the accessories such as digestion tank or

platform. If happened, please wipe clean immediately with a soft cloth or paper.

WARNING: The 220V voltage may cause electrical shock hazards, please make sure

the power switch is in the state of closed (0) before connecting the power cord.

uMake sure power supply and ground wire is normal.

uMake sure the voltage of power supply is normal.

uInsert two sides of the power cord respectively into the power grid socket and

the power supply socket of the instrument.

7) Make sure the connection of the power line and the ground wire is normal. Put the

power switch to “1”, the instrument is powered on and enters the Automatic System

Check Interface. When system checks to “Pressure detecting…” it stops and prompts

“no digestion tank” if you don’t load the digestion tank before power on, you can load

the assembled digestion tank and close the door and press the button of [Check] to

continue the pressure checking. If you don’t need to check the pressure you can press
