Questron Technologies Corp.-Express Microwave Ashing System-QAsh 1800
Our custom designed QAsh software allows the user to make batch fi les that control all aspects of an ashing process. The samples are ramped or held steady at specifi c temperatures in multiple steps as a function of time according to easy-tomake batch fi le program. Further, the blower motor and fl ow of air to the sample are both under the control of software. This way, precise, reproducible ashing of samples is possible from day to day. All sample ashing data is collected and stored in hard disk for archiving or future viewing in graphical or tabular formats. Several different batch fi les may be made in order to accommodate the varying types of user sample types. If desired, the sample program can be modifi ed at any time, even during running.
Microwave ashing is an innovative analytical sample preparation method that replaces the traditional ashing technique using a resistively heated muffl e furnace. While maintaining the basic tried and tested principles of ashing, replacing the resistive heating with microwave heating offers distinct advantages, chief among them being speed, reduced energy cost, high sample throughput, better reproducibility, cleaner working environment and increased operator safety.
As opposed to acid digestion, measuring ash content is inherently a simpler process that is performed in laboratories worldwide on a daily basis – mainly for process and quality control applications. It is a routine procedure in such diverse fi elds as petroleum industry, pharmaceutical applications, food products, plastics manufacturing applications and waste management industry.
As a manufacturer of microwave digestion products, Questron Technologies Corporation has applied its considerable expertise in employing microwave ovens in the analytical laboratory to the ashing process. The result is our QAsh 1800 Microwave Ashing System. QAsh 1800 is an excellent and highly effi cient alternative to conventional muffl e furnaces. Employing the same crucibles that are used in conventional ashing systems, the QAsh 1800 is able to offer a better way of performing the old quantifi cation procedure of ashing, all under the control of our custom QAsh software running in Windows® XP™ and Windows® 2000™ operating systems.
By using microwaves as a source of heat in our QAsh 1800, ashing times for many sample types are reduced by over 90 percent, resulting in drastically higher throughput rate and more effi cient use of operator time. Our QAsh 1800 employs a robust 1800 watts of microwave energy under QAsh software batch fi le control that can easily heat up 10 samples to 1200°C in under one hour.
