“The PTI QuantaMaster series modular design offers reassurance that your system can be easily customized and adapted to your growing research capabilities.” PTI QuantaMaster Series The PTI QuantaMaster series of research grade spectrofluorometers are multidimensional systems for photoluminescence measurements. The foundation of a fluorescence spectroscopy laboratory is built on steady state intensity measurements such as wavelength scans, time-based experiments, synchronous scans and polarization. The PTI QuantaMaster series ensures you get the best possible results for all these...

Sensitivity The industry standard for sensitivity is a signal to noise ratio calculated from a water Raman spectrum. Using this standardized test (see our technical note "SN Determination for PTI QuantaMaster Fluorometer,") our signal to noise ratio is >20,000:1. The high sensitivity of the PTI QuantaMaster fluorometer is no accident. It is achieved by intelligent engineering of the Xe arc lamp illuminator featuring an ellipsoidal reflector with the highest possible light gathering efficiency of 67%, and focusing the light in a tight spot at the monochromator slit. As a result, the standard...

Suppression of stray light is one of the most critical factors when measuring highly scattering, or low quantum yield samples. Every PTI QuantaMaster series spectrofluorometer is custom made with the highest quality optics to insure the lowest amount of scatter. The asymmetrical monochromators are coma-corrected and individually optimized for purpose as either excitation or emission monos, ensuring the lowest amount of stray light contamination for the best detection of the true fluorescence signal. The PTI QuantaMaster series boasts an impressively high stray light rejection: >1x10-6 in a...

Spectral Range and Signal Detection Excitation and Emission Correction For most applications, the typical detector employed is a PhotoMultiplier Tube (PMT). Every PTI QuantaMaster features a highly sensitive PMT, with the option of an analog or digital output. The PTI QuantaMaster Series offers you the ability to customize the system to meet your applications needs. Digital detection, or photon counting, offers the highest sensitivity as it records single photon events. The analog detection measures the current that is generated on the PMT anode, and provides for additional detection gain...

The QuantaMaster 400 steady state spectrofluorometer is one of the most sensitive bench-top fluorometers on the market today. Its signal to noise is >20,000:1, allowing the minutest traces of fluorescent materials to be detected and identified in samples. It features state-of-the-art high throughput monochromators with a triple motorized grating turret for easy extension of the spectral range, and motorized flipping mirrors to make it easy to work with additional light sources and detectors. Its high performance and open architecture makes it suitable for practically all possible...
