Working principle of HR-LCMS: Comprising two components, a liquid-phase separation system and a mass spectrometer, liquid chromatograph mass spectrometers (LC -MS instruments) couple sample fractionation and analysis. The separation can be accomplished via standard liquid chromatography, HPLC, UPLC, or even nano-LC. Any liquid-phase separation will do, so long as its output can be directed into the mass analyzer (for instance, via an electrospray ionization source). The mass spectrometer is similarly flexible, ranging from the simplest single quadrupole to a Fourier transform ion cyclotron resonance instrument. In a liquid chromatograph mass spectrometer the column flow is continuous, meaning the mass analyzer must be fast enough to thoroughly analyze one peak before the next one comes off the column.

Applications: HR-LCMS is a powerful technique that has very high sensitivity and selectivity and so is useful in many applications. Its application is oriented towards the separation, general detection and potential identification of chemicals of particular masses in the presence of other chemicals (i.e., in complex mixtures), e.g., natural products from natural-products extracts, and pure substances from mixtures of chemical intermediates.

SHELXTL S/W, Cryostream-700plus extended range low Temperature

Working principle:

X-ray diffraction is based on constructive interference of monochromatic X-rays and a crystalline sample. These X-rays are generated by a cathode ray tube, filtered to produce monochromatic radiation, collimated to concentrate, and directed toward the sample. The interaction of the incident rays with the sample produces constructive interference (and a diffracted ray) when conditions satisfy Bragg's Law (nλ=2d sinθ). This law relates the wavelength of electromagnetic radiation to the diffraction angle and the lattice spacing in a crystalline sample. These diffracted X-rays are then detected, processed and counted. By changing the geometry of the incident rays, the orientation of the centered crystal and the detector, all possible diffraction directions of the lattice should be attained.

Applications:

Single-crystal X-ray Diffraction is a non-destructive analytical technique which provides detailed information about the internal lattice of crystalline substances, including unit cell dimensions, bond-lengths, bond-angles, and details of site-ordering. Directly related is single-crystal refinement, where the data generated from the X-ray analysis is interpreted and refined to obtain the crystal structure.
