Time to Upgrade? Water Purification Systems

New Regulations, Increased Use, Flagging Performance and Significant Maintenance Main Drivers to Buy

Like other types of equipment, when the cost to repair the unit starts to represent a significant portion of the price to buy new, it’s probably a good time to upgrade your water purification system.

Overall, determining exactly what their current and future needs are will help users make the best choice on whether or not to upgrade, and get the highest value.

Considerations before buying:

  • Always compare the cost for upgrading parts to the cost of a new system, but also include the value of the warranty
  • Ask about reliability and available service for the unit
  • Find out the cost of consumables
  • Costs will vary depending on the features available with the system
  • Some vendors offer systems that can be “incrementally” upgraded, which can save you money
  • All "purified water" is not "equal"
  • Be sure to establish repair vs. replace thresholds for your equipment

Plenty of discussions are happening on LabWrench all the time. We have many questions come in daily from users that are seeking advice from fellow users and lab professionals on LabWrench. Can you help any of these users find the answers they are looking for?

Free Varian Atomic Absorption Spectrometer, SpectraAA400
The Bren School at University of California, Santa Barbara, has a Varian Atomic Absorption Spectrometer, SpectraAA400 that we would like to give away.  The equipment functioned properly when last used.  The unit includes a PSC-56, Programmable Sample Changer, and the PC to run the unit.  You must pay for shipping costs. Respond here.

GC Derivatization Reagents with Hewlett Packard 5890 Series II
There are a few reagents used to analyze samples for amphetamine metabolites by GC-MS. These and other drug metabolites are often found by similar methods. Prior to analysis of these compounds found in urine, silyl derivatization is being performed in our lab to improve analyte volatility prior to analysis by GC-MS. We are using BSTFA (more info) and MSTFA (more info). These derivatization reactions are being conducted with and without TMCS (Trimethylchlorosilane). I am looking for a proven method for using these derivatization reagents (MSTFA, BSTFA, and TMCS) with isotope labels. Specifically, I am trying to compile literature on deuterium labelled varieties of these compounds. If you have experience with quantification of analytes with these derivatization reagents, and you know of good references, it would be much appreciated. Help this member.

Question regarding Applied Biosystems StepOne Real-Time PCR System curves
We want to do an absolute quantification of a certain gene, we already do the standard curve for these target and we want to know if there is a way to use these curve for quantify an unknown sample in a different run? or we have to run the curve every single time? Share your knowledge.

We have so many questions filling our forums that sometimes questions can be missed and go without answers. Can you help us provide answers for these users with unanswered questions?

How do I increase the water feed pressure on a Siemens Water Technologies Protegra CS ?
My company had bought a PRO EDI 750 system. Now we realize that the pressure of feed water is at 1.2 bar and we want to install a booster pump to increase this feed water pressure.
May I know where should we install the booster pump? Just after the incoming city water or just before the Siemens system (after pre-filter, carbon filter, softener and fine filter)?  Should I install a pressure tank just before the booster pump?  Help this member

ELGA PURELAB Option S/R 7/15 feedwater quality
I am qualifying (IOQ) a R15 unit.  I have sampled and had tested the feedwater for quality.  We had tested for heavy metals by a contract lab and they tested for a multitude of metals,  I have done some research on the net and the heavy metals test is typically conducted for Cadnium (Cd), Lead (Pb), NIckel (Ni), Zinc (Zn), Copper (Cu) and Chromium (Cr).  Is that correct?  If so, the limit specified in the documentation is ≤ 0.5 ppm.  We are getting 213.2 ppb which corresponds to 0.213 ppm.  What is the effect on the system as for our qualification it would be a deviation.  Respond to this member.
