flexible sample changer
With the SAC80’s 15-place capacity, he analyses ten samples,
along with one duplicate sample per batch, using one beaker for
electrode rinsing, one for certified standard solution that’s
automatically run every ten samples, and two for pH buffers. He
completes these determinations about three times a week, for 30
measurements. “And I really like the software,” he continued.
“We can customise the titration programme for the sample –
there’s flexibility we didn’t see in other autotitrators.”
Dedicated
software is a bonus
TITRAMASTER 85 Titration Software enhances the system. Mike added
it to simplify retrieval and management of measurements from his
PC. “We sample and analyse up to eight water sources, ground
and surface, at least every other week. With this software, there’s
a sense of ownership of the data: we can label samples specifically,
graph and print out easily, and make more detailed evaluations.”
Lab analysts use pH and alkalinity determinations to calculate the
Langlier (corrosivity) Index in a spreadsheet, for water treatment
process control and for reporting to the state. The information
also helps operators monitor softener operation and support customer
inquiries.
A compact system
“We were using this same amount of space for all the equipment
needed for manual titrations,” affirmed Mike. “Now,
in the same space we have better throughput, more accuracy, and
automated data handling.”
