Photon Technology International Pushes the Limits of Detection to Attomolar Levels

(Nanowerk News) Photon Technology International (PTI), a known innovator in fluorescence with over 26 years of experience is once again expanding the frontiers of detection to attomolar levels with its new QuantaMaster™ 40 Spectrofluorometer.
While typical spectrofluorometers struggle with picomolar detection, which is already a very tiny amount, the new PTI system can now detect attomolar amounts, allowing it to detect six orders of magnitude (a million times) less. Smaller is better particularly when it comes to detection. The ability to detect such small amount of substances will greatly benefit researchers in: medicine, industrial processes and environmental monitoring to name just a few. The QuantaMaster™ 40 is the most sensitive fluorometer on the market today! The QuantaMaster™ fluorescence spectrofluorometer series in addition to its high performance, offers the ultimate in flexibility because of its unique modular "Open Architecture" design.
The QuantaMaster™ series is one of four products lines from PTI. The other product lines are TimeMaster™ for fluorescence lifetimes, RatioMaster™ for ionic detection and ImageMaster™ for fluorescence imaging. For more information about PTI fluorescence solutions, log onto or call 609-894-4420.
