In comparison with resistively heated muffle furnace, QAsh 1800 employs 1800 Watts of

magnetron power which results in faster ashing, thereby reducing ashing times by up to

90%.

Working under QAsh software, the built-in powerful exhaust blower of the QAsh 1800 directs

gaseous components of the sample through a gas hose to safe disposal such as a fume

hood. Furthermore, a source of compressed air or Nitrogen gas can be introduced into the

chamber, which draws out the fumes and soot and results in a cleaner oven interior.

The QAsh 1800 ceramic muffle furnace is an excellent heat insulator. It easily allows the

microwave energy to enter the samples contained within, but keeps the heated samples from

losing their heat to the oven or the laboratory. This saves on air conditioning costs and

results in more comfortable working conditions.

FEATURES

The samples are ramped or held steady at specific temperatures in multiple steps as a

function of time. The QAsh 1800 employs a robust 1800 watts of microwave energy

that can easily heat up 10 samples to 1000°C in 25 minutes.

SOFTWARE

Our custom QAsh software runs in Windows^{® XP™ and Windows® 2000™ operating}

systems. It allows the user to make batch files that control all aspects of the ashing

process. The blower motor and flow of air to the sample are both under the software control.

All sample ashing data is collected and stored for archiving or future viewing in graphical

or tabular formats. Several different batch files may be made in order to accommodate the

varying types of user sample types. The sample program can be modifiedat any time, even

during running.
