introduction
Super microwave digester (hereinafter referred to as“Super microwave”)bySingle reaction chamber prepressionThe unique design overcomes many traditional microwave digesters (hereinafter referred to as“Traditional microwave”) disadvantages. In the past, we have given a general introduction to the excellent characteristics of super microwaves ("A Brief Discussion on Super Microwave Dissolution"）, interested friends ask us questions:“In the past, I used traditional microwaves to process samples, and could only process one type of samples at a time, and there would be inevitable temperature and pressure differences between different digestion tanks. If the amount of acid added is slightly different, the digestion effect will be very different. Do you think super microwave can handle multiple different samples at one time? Is it true?”Regarding this, I can tell you responsibly: It is true! As the saying goes,“The only thing that can be said on paper is shallow, and you must practice it yourself to know it.”! Next weAt onceUse experiments to prove that what we say is true!
1. Materials and Instruments
In this experiment, we used BooinstrumentThe company developedSupermate 7xSuper microwave digester, for15Different types (foods and additives, medicines (materials) and auxiliary materials, health products and solid beverages, etc.), different weighing volumes (0.2-1.0g) sample (picture1and table1），See if the super microwave can withstand this test.
picture1Different types of samples
The digestion temperature of these samples using traditional microwave treatment is mostly at180-200℃There are different temperatures, but the pressure in the tank rises sharply due to excessive temperatures, which poses a safety risk of explosion or leakage. Moreover, excessively high temperature can also damage the digestion tank, affecting the normal operation and service life of the equipment.Figure 2 Samples after adding samples and nitric acid (sample holder)（2）Everything is ready, click“start up”It officially begins to dissolve, thenyouYou can go fishing……3.

Table 2 Digestion effect of different sample types and sample sizes
The digestion effect of most samples is very ideal……，Even if the individual sample quantityGundam1 g，It can also be completely eliminated. That is to say:Super microwaves have powerful digestion capabilities and can handle multiple types of samples at the same time, without considering sample classification issues。
Of course, you may have noticed it too.15Among the samples there are3The digestion effect of one sample seems to be unsatisfactory(surface2），As forreasonWell, it's a purple drop……
1) Collagen peptide and Natto Red Quo (6and8Sample number) did not digest completely due to insufficient acid addition. It is obvious that as long as the weighing volume is reduced properly orincreaseAdd acid amount to solve the problem (you need to pay attention to digestion during the periodvolumeDo not exceedSample tubeof1/2, while increasing the amount of acidEvenChangeforLarger volumesampleTube);2) Hollow Capsules (15The number sample) is because it has not been addedHFAnd a few appearedTiO2Precipitation can be adjusted by adjusting the digestion solution formula (if introducedHF, the quartz reaction tube should be replaced withPTFEreaction tube).Visible, althoughVery few samplesOn the surfaceDissolve effect“Bad”，But in factJust simplelandAdjustmentoneDissolvetryTypes of agents、ProportionOr sample tubeIt can be solved!It can be said that the above small questions are not a problem either.For the above samples that require increasing the acid amount or use HF to complete digestion, our BoAu Company is equipped with larger volume (50/70 mL), multiple materials (quartz glass and PTFE) sample tubes and their sample holders (same or different volumes or specifications can be placed at the same time), which are available for you to choose from! To this end, we will also launch a special application case with larger needle sample sizes and more acid volumes. Please pay attention!all in all,WordandtotalWell, the digestion effect of super microwave is realdropThat's itPerfect！Please don't hesitate to contact us,If you are in need of assistance!
The SUPERMATE 7X Super Microwave Digestor (Figure 12) independently developed and produced by BoAu has been officially released. We look forward to bringing you the ultimate digestion experience!
