LAB ASH
Laboratory measurement of ash content

The LabAsh is a laboratory instrument providing a quick measurement of the ash content of a crushed sample of coal. It is easy to use and provides accurate results within a few minutes.

The LabAsh has been successfully sold to many countries around the world. It has proven to be an economical choice for many laboratory customers.

There are no radioactive sources - the LabAsh uses Natural Gamma Technology.

The LabAsh is in daily use in laboratories around the world.

Operation

The LabAsh comprises two main parts: a Sample Measuring Chamber and a Display Unit. In addition there is the sample beaker and a recently introduced Joggle Table.

The Sample Chamber is a substantial lead walled cylinder containing a scintillation crystal and associated electronics.

The crystal is positioned vertically in the centre of the chamber so that when a special beaker containing the coal sample is lowered into position the crystal is evenly surrounded by the sample.

The mains powered Display Unit provides the user interface and is housed in a case suitable for desk or bench top operation.

The recently introduced Joggle Table is used to provide uniform compaction of the sample during the beaker filing process.

This has enabled users to fill the beaker faster and more uniformly, leading to more consistent ash results.

Accuracy

Applications at several sites have shown that unbiased results with a precision of 0.65% ash can be achieved in less than 10 minutes.

Features

Simple to use
Accurate results within a few minutes (<3 minutes)
Stores up to 600 sample measurements
Facility to include: date, batch and sample name into each record
Easy to calibrate on site using normal production samples
Can store up to 9 different calibrations for multi-source applications
Can download data to a computer

Applications

Any coal where a crushed sample is available
e.g. final product
PSF
washed fines
imported coal etc.

Benefits

Quick ash results from the hourly samples (less than 5 minutes compared with at least 2 hours to obtain the in-house lab analysis or several days for an off-site laboratory)
Faster and therefore more accurate control of quality
Reduce in-house sample analysis from hourly to split shift leading to less effort by laboratory staff thereby achieving lower costs
Provides an independent check on both in-house and commercial sample analyses - enabling precision of all measurement methods to be assessed under ISO15239
