 PTI is the only company to offer logarithmic time scaling due to their unique technique. This illustration show how you can acquire and analyze vastly different lifetimes on complex decay kinetics with several different lifetimes as well as rise time. This is done with a small number of data points in a single decay acquisition. Sample courtesy of Dr. Mary Berry, Univ. Of South Dakota. |
PTI offers three different systems for measuring time resolved fluorescence, ensuring that you can pick the system that is best for you. All three systems are time-domain systems acquiring the real decay curve and providing comprehensive decay analysis tools including distribution analysis using either MEM or ESM, and FRET calculators. PTI LaserStrobe: PTI's LaserStrobe fluorescence lifetime system is the system of choice for the research lab that is working with low concentrations or weak emitters. With high peak power, tunable 1 nanosecond laser pulses for excitation anywhere from 235nm to 990nm, and PTI's patented time-domain stroboscopic detection technology this system is able to handle even the most demanding fluorescence lifetime measurements. The LaserStrobe has excellent sensitivity down to 7pM fluorescein or better and can deconvolute fluorescence lifetimes as short as 100 picoseconds. Taking advantage of PTI's patented stroboscopic detection, this system can collect data in a logarithmic time scale and it can acquire time resolved emission spectra (TRES) directly. These are two unique benefits only available from PTI. More product information |

Interested in FLIM? PTI also offers a microscope version of the LaserStrobe system for fluorescence lifetime microscopy. More product information PTI LEDStrobe: PTI's LEDStrobe is ideal for users that want a simple and affordable fluorescence lifetime system. With interchangeable LED's and laser diodes selectable from 250 to 670nm, and PTI's patented time-domain stroboscopic detection technology the LEDStrobe is a system that literally anyone can use to perform a broad range of fluorescence lifetime experiments. The LEDStrobe has good sensitivity down to 1nM fluorescein or better and can deconvolute fluorescence lifetimes as short as 100 picoseconds. Taking advantage of PTI's patented stroboscopic detection, this system can collect data in a logarithmic time scale and it can acquire time resolved emission spectra (TRES) directly. These are two unique benefits only available from PTI. More product information PTI PicoMaster: Did you know that the Founders of PTI also developed and introduced the world's first commercial Time-Correlated Single-Photon-Counting (TCSPC) system in the early 1970's? This year PTI has brought back TCSPC in a big way with the introduction of the PicoMaster series. The PicoMaster utilizes interchangeable LED's and laser diodes selectable from 250 to 670nm, along with TCSPC detection and electronics. The PicoMaster allows you to measure fluorescence lifetimes down to 10 ps or to detect in the NIR out to 1,700nm. The system is controlled with the same trusted PTI software and is even capable of measuring the entire range 10 ps to 20 us. For more product information, contact QuantaMetrics. |
