Our highest performing model with a wide range of accessories for maximum flexibility.
The J-1500 allows for the maximum flexibility to upgrade your CD system with different measurement techniques. While the standard measurement modes are CD, LD, and absorbance, up to four simultaneous modes can be measured when combined with a wide range of sampling accessories.
The wavelength range has also been significantly extended, allowing measurements to be obtained in both the vacuum-UV and NIR spectral regions using the standard PMT detector (163 – 950 nm) and an optional InGaAs detector (up to 1600 nm). Additional features now allow researchers to optimize their parameter specifications in order to obtain data with the highest resolution and S/N performance for a specific application set.
● Wavelength range 163-950 nm (optional 1600 nm)
● Low stray light
● Simultaneous Multi-Probe (SMP): CD, LD, fluorescence, UV-visible, absorbance
● Integrated Hg lamp for wavelength calibration
● Three scanning modes: auto, step and continuous
● Highly efficient nitrogen purge system: low volume monochromator designed using a flow simulator
Enhanced Vacuum-UV Measurement
α-pinene enantiomers (gas phase) showing excellent performance in the Far-UV region.
CD spectra of Human Serum Albumin (Helix rich), Concanavalin A (β-sheet rich) and Trypsin inhibitor (Random rich) in water with excellent signal to noise to 174 nm.
The same α-pinene sample showing similar superior performance in the vacuum-UV region down to 163 nm.
The only CD instrument designed to explore the structure and stability of biomolecules by providing the maximum signal-to-noise under highly absorbing, low light intensity conditions of the far-UV spectral region.
Unlike some detectors which only provide good signal-to-noise for low absorbing materials, the J-1000 Series circular dichroism spectrophotometers use high dynamic range detectors to obtain high quality spectra of samples with excellent signal-to-noise, especially for highly absorbing materials found in the far-UV.
