With specialised program, they are often used to measure thin movie thickness, colorimetry plus more. The following links have more information:
The Charged Aerosol Detector (CAD) is often a detector that is certainly used in HPLC to measure the level of chemical substances in a very sample by developing billed aerosol particles that happen to be then detected employing an electrometer (3).
Because of its large sensitivity, the fluorescence detector is especially handy for trace Assessment, or when both the sample size is modest or maybe the solute concentration is extremely low.
Manual columns together using a packing station offer an financial toolbox for column packing as well as the ability to build and improve column packing as expected for specific processes and the flexibility.
Procedure development and producing could possibly have to handle many different resins starting from tiny to substantial particles, from slim to huge distribution of particle dimension and from delicate to rigid, maybe even brittle particles.
A refractive index is often a dimensionless number describing how fast mild propagates through a medium compared to the vacuum. Snell's legislation defines the refraction of sunshine as it crosses the border between media with different refractive indices.
I am able to revoke my consent at any time with result for the long run by sending an e-mail to unsubscribe@sartorius.com or by clicking on the "unsubscribe" connection in e-mails I've check here been given.
Ideal for high-sensitivity measurements of molecules in complex biological matrices where by analyte concentrations can span various orders of magnitude

Vitrinite reflectance, stage counting and fluorescence of coal, coke and petroleum source rock with
The units are engineered to have no transferring sections or detector sockets, make use of a ruggedized aluminum enclosure and an built-in A/D digitizer for unmatched durability and high-quality that out performs any instrument in its class. Various models present typical, concave grating, or higher resolution (HR) optics for selected spectral ranges.
