Optimal excitation is generated by brilliantly intense and perfectly stable LED sources.
Maximum emission sensitivity is achieved using our highest throughput monochromator and a photon counting detector so astonishingly good that we refer to it as Her Majesty.
An equally useful detector with 1/1000th the sensitivity is available at a much lower price point, perfectly suitable for many laboratories.
Instead of the high-speed 50 kHz photoelastic modulator used in other CPL systems, the CPL Solo NIR selects between left and right circularly polarized light using a quarter-waveplate. This switching can be fast or slow according to experimental needs. One can even choose to measure only Lum(L) or Lum(R) for a given experiment.
Our scripting data collection software allows you to define an arbitrary number of “time zones” across the spectral region of interest, allowing you to zip along quickly in zones where the emission is large or of no interest and then change to an appropriate faster or slower acquisition rate in the other zones.
This time-scripting is the ideal way optimize time spent within spectral zones (spectral ranges) from the irrelevant to the most critical, never spending too much or little time anywhere. Scripts take moments to produce and can be saved or edited for subsequent experiments.
As with all OLIS CD and CPL spectrometry systems, data acquisition is entirely digital, utilizing raw signals from the detector rather than pre-processed signals passed through a lock-in amplifier that are used in non-OLIS spectrophotometers.
Only the OLIS method captures raw Lum(L) and Lum(R) signals which are used to collect CPL. All other methods employ a lock-in amplifier and G-factor corrections.
The CPL Solo NIR can be enhanced for phosphorescence lifetime, so that one knows if he is collecting CPF or CPP. Also, excitation can be polarized or unpolarized.
