Mercury disolved in water

Mercury disolved in water

Mercury disolved in water

(OP)
Hello all,

I am googling to find an analyzer that can measure  quantity of mecury disolved in water.
Does anyone have informations on that kind of analyzer?

Thanks a lot guys.

You are right IRstuff.

What I'm looking for is an in-line device that can continuously measure the traces of Hg in water.It should be able to measure down to 0.001 mg/l of hg in my water.

By the way, I am looking into the 2537 A from TEKRAN. It's supposed to be able to fill the bill. Any experience with?

Thanks.

Check with EcoChem Analytics to see if their Atomic Absorption Spectrophotometer can be applied to water.  281 338 9888 www.ecochemanalytics.com

Thanks all. JLSeagull, I've sent an email to EchoChem to get some more infos on their HG-Monitor 3000. Thanks a lot.

Cheers.

Correct IRstuff, that's what the article implies. But the thing is, TEKRAN has used its 2537A to monitor Hg in the Canadian Artic waters. It might not be exactely the same application like mine, still I've sent them an email to know more about their product. who knows!!!!

Thanks a lot.

RE: Mercury disolved in water

So, that might be a way.  If you have a side chamber that allows you to agitate/heat the water, you might get sufficient emission of mercury to get readings.

you are right IRstuff, the guy has just anwered me saying that he can't measure traces of Hg in water. The only way to do it is via a customized ($$$$) solution.

I've  also (that for JLseagull)  received a negative answer from EcoChem. They just focus on gases.

Thanks guys for help.

Guys FYI just in case...
I found a company that can supply an on-line Hg analyzer. Go to www.mercury-instruments.de

Cheers.

Dembous,
        A few years back I was involved in remediating an old plant where they used Mercury cells. We pumped water out of the ground and removed Hg. Because we were unable to find an on-line analyzer I built one based on a lab style measuring cell and PLC. It measures in the low ppB range.
Simple enough for the operators to troubleshoot.

RE: Mercury disolved in water

Dembous,
                  I took a look at your suggestion, it is very similar to the solution I came up with except I used a standard PLC so it was easy to connect into the control system. The measuring cells put out a significant mV that can be measured directly by the PLC without any additional electronics. It took a bit of work to get right but the end result allowed the plant to run 24 hours rather than have to have lab staff on hand. The chemicals are quite nasty, requiring a separate  enclosure for the electronics.
If anyones interested further.
