Advantages of microwave sample preparation:
●
The activation characteristic of microwave enables easier sample
dissolution and chemical reaction. Combined with sealed container to
increase pressure and temperature, it greatly increases the speed of
chemical reaction and shortens the sample preparation time to 1/10 of
traditional method.
●
Volatile elements or components will not be lost in the process of sample
preparation. Low reagent consumption, reducing blank value and waste
liquid pollution to the environment.
●
Lessening harm of acid mist to human bodies.
●
Eliminating contamination of environment to the sample.
●
Less interference factors, easier sample control and automation.
MDS-6600/8600 Microwave Digestion System
Instrument features: (MDS-6600/8600)
●
Large screen LCD displays pressure curve and parameters in real time,
enabling clear under standing of the reaction status. Reaction results
stored with chemical reaction characters, & can be recalled at any time.
●
10 sets of pre-stored digestion method satisfy routine sample digestion
needs. Each set of method includes 5-step program (microwave power,
total time, pressure value and pressure keeping time) to control the
reaction, keeping uniform conditions for different batches of sample.
●
The pressure control vessel and other sample vessels are under the same
conditions, realizing true real time monitoring & over-pressure protection.
Setting target pressure of each step at an increment of 0.1 for more
accurate control. 10 double-cup vessels can be used at the same time
for high efficiency of sample preparation.
●
One second time-base design realizes fast and smooth microwave sample
preparation.
●
The cavity wall is coated with corrosion-resistant material, preventing acid
& alkali corrosion. The system is designed with microwave leakage prevention.
●
New-type rotating microwave provides even heating and easy control.
●
Specially designed exhaust fan can get rid of acid mist easily.
●
Adopting the newest technology of ideal gas pressure control system, real
time pressure monitoring device and over-pressure protection,realizes easy
and safe operation.
