  1. What is microwave ashing? Microwave ashing​ is nothing but a simple and commonly used technique throughout the world by elemental scientists to dissolve heavy metals. They do this in the presence of organic molecules prior to analysis by ​inductively ​coupled plasma, ​atomic emission​​measurements​, or ​atomic absorption​. This technique is usually accomplished by exposing a sample to a ​strong acid​ in a closed vessel. After placing the sample in a closed vessel, with the assistance of microwave irradiation the pressure as well as temperature in raised. The speed of thermal decomposition of the sample and the solubility of heavy metals in the solution is increases by the increase in the temperature and pressure of the low ​pH​ sample. Through elemental techniques it is possible to quantify the sample once these heavy metals are in the solution.​ QAsh1800

  2. The use of​ microwave ashing technology​ for the purpose of ashing metals has resulted in a significant advantage in terms of internal quality control and in case of complex sample preparation, it has simplified the process along with ensuring the safety of the analyst. But still many laboratories use the decades old traditional ​electrical furnaces or muffle furnace when it comes to ashing the sample for the process control purposes. There are huge disadvantages in using this technique for ashing samples. They are very time consuming process when compared to the microwaving ashing, more often they end up consuming hours per run. Eventually, when the furnaces run for a long time they end up consuming high amount of energy. And this in turn results in high operating costs. In addition to all this, the usage of traditional furnace have a tendency to diffuse heat and odors. This diffusion of heat and odor can result in an uncomfortable working environment. In order to avoid the high energy usage, high operating costs and increase total cost effectiveness of the process, deploying microwave ashing technology would help.
