Not Your Average Filter – Specialized Features of Luminultra’s Quench-Gone Filter

  Anyone looking through our line of adenosine triphosphate (ATP) test kits will probably notice one particular item that is included in some methods, but not in others: the Quench-Gone syringe filters. So, what purpose do they serve and why are they only used in some methods? A major advantage of LuminUltra’s 2nd Generation ATP… Read More

What Can 2nd Generation ATP Do for an Operator or Field Technician?

  From the editor: Does your current (microbial) testing program, give you all the answers you need? Read on to find out how this new generation of ATP testing can provide useful insights on the spot. It’s important to start with the fact that this is not a regulatory test. This technology won’t replace any required… Read More

The Overlooked Importance of Calibrating Your Enzyme

  One of the major benefits of LuminUltra’s 2nd generation ATP monitoring over existing technology (i.e. ATP pens) is the normalization of enzyme activity. At the microbiological level, knowing how active the enzyme is at the time of testing offers significant benefits for both data collection and analysis. Given this, LuminUltra’s 2nd Generation ATP test… Read More

What is a linearity check and why should you perform one on your luminometer?

  Before our PhotonMaster luminometers head out the door they are all rigorously checked in our hardware lab; sensitivity and linearity tests confirm that all units meet the required specifications for background levels, low detection limits and linearity. The linearity check confirms that the curve (Light output vs ATP standard concentration) is linear from 0.01… Read More

Most Wanted Microbes – Kouleothrix (a.k.a. Roseiflexus)

  From the editor: This is the second post in an ongoing series profiling microorganisms of particular significance in water and wastewater systems. In this series we will cover microorganisms of many types including some that are beneficial, inhibitory and pathogenic.  Kouleothrix is a filamentous organism found in wastewater treatment systems. They appear as thread-like… Read More

Most Wanted Microbe – Escherichia coli

  From the editor: This is the inaugural post in an ongoing series profiling microorganisms of particular significance in water and wastewater systems. In this series we will cover microorganisms of many types including some that are beneficial, inhibitory and pathogenic.  Escherichia coli or E. coli is a species of bacteria commonly found in the… Read More
