  Mds-6 automatic frequency conversion temperature and pressure dual control microwave digestion / extraction instrument is the sixth generation product launched by Shanghai Xinyi Microwave Chemical Technology Co
, Ltd
and is an advanced microwave sample pretreatment equipment in China
She uses the two international advanced technologies of power automatic frequency conversion control and non pulse continuous microwave, which won the BCEIA Gold Award of China analysis and Testing Association, to realize the closed-loop automatic feedback control of microwave power with reaction temperature and pressure, and display the curve of temperature and pressure rise in real time
Three built-in software control modes (pressure master, temperature master and microwave extraction) are applicable to the digestion and extraction of various organic and inorganic samples
They are not only compatible with the closed containers and digestion methods of the traditional pressure control mode, but also applicable to foreign standards and methods of temperature control mode (such as EPA standards and international ASTM standards of the U
S
Environmental Protection Agency)
Their safety performance has passed the CE recognition of the European Union

matters needing attention:
1
In addition to sample weighing, all pretreatment tests shall be carried out in the fume hood
All cleaning must be protected in advance, and gloves and masks shall be worn as far as possible

2
The digestive tube shall be washed with clean water and rinsed with primary water for three times

3
The digestive tract cannot be brushed with a brush

4
Before using the digestion tube, it is necessary to dry it on the acid extractor (acid extractor) or throw out the residual water on the inner wall of the tube, and wipe the outer wall of the digestion tube with paper; Note: the outer wall shall be wiped dry with paper, and the inner wall shall be thrown as far as possible without water droplets flowing out, otherwise it will have a certain impact on the results

5
Gloves are required for sample weighing

6
The sample shall be placed at least one-third from the bottom of the sample digestion tube and two-thirds from the top of the digestion tube, otherwise it will adhere to the wall and flush unevenly

7
Static electricity will be generated when powder samples are weighed directly
Try to weigh them with weighing paper

8
After weighing, add reagent into the digestive tube
You need to wear a double-layer book cover to prevent the test agent from corroding your hands

9
If there is nitric acid in the reagent, superior purity or higher purity is required

10
When washing the sample digestion tube with reagent, do not directly insert the head of the pipette gun into the inner wall of the digestion tube to stick to the wall, so as not to scratch the inner wall to damage the digestion tube and affect the test results

11
Before adding reagent, try not to directly absorb it in the original reagent bottle, and try to pour it into a reagent bottle without pollution, and pour it as you use it

12
After the reagent is added, shake it well and let it stand for about 5 minutes

13
Add the inner cover and the outer cover, and let it stand for about 10-15 minutes
14
The microwave digester needs regular maintenance to keep the interior dry and clean

15
After digestion, the transferred sample needs to be in a transparent state, otherwise it is considered as incomplete digestion
