Challenges the customer faced

According to former development manager for Sustainagro, Adrian Parker, before the lab had the G100 and could measure in real-time it used a titration method:

'It took ages, several hours, just to do one.'

G100 CO2 analyser

How the product helped

The G100 has made the process much quicker; the lab can have several different flasks and compost samples running.  They have to be left for three days to stabilise before taking measurements.  Darcy Bertie, managing director comments:

'I simply move the analyser input tube between the flasks and measure each, as I need, in a moment, in seconds. That's improved efficiency by more than 50 percent which is a lot of money in this business and means we can offer customers a much faster and more accurate service.'

Bertie and Dr Jane Leitch, principal research scientist for Sustainagro both agree that this procedure will be beneficial to both sides of the business.

'The G100 is really easy to use. From taking it out of the box I had totally understood it in less than an hour. It was really easy. There are a couple of User Manual discs with everything you need and you just set the G100 and start it - and you are up and running. It has been working really well.  Compost is very moist which the filters handle and the G100 has built in moisture removal,' said Adrian who keeps the G100 running continuously using the data logging facility and downloads to a PC.  He said the service and support from his supplier GEM Scientific has been excellent in making sure the moisture filters and moisture removal was working perfectly with such a wet environment.
