Intuitive method to help you pick out the appropriate chromatography column on your biopharmaceutical purposes.
The wavelength of light absorbed depends on the construction in the material. Light-weight within the ultraviolet to seen range is used for absorbance detection.
Agilent LC systems arrive which has a total complement of instruments required to complete common maintenance and operation procedures. In the event you have to have further or substitute instruments, Agilent provides a collection of significant-precision, high-high-quality, stainless-steel instruments.
Mass spectroscopy detectors present extremely higher selectivity and sensitivity and their detection relies on molecular fragmentation by electrical fields and separation according to the mass to cost ratio of fragmented molecules.
Agilent HPLC lamps are created in an ISO 9001 certified setting and so are thoroughly traceable throughout every single stage with the manufacturing process. Just about every lamp is separately examined and Licensed with a Certification of study to make sure it meets the stringent Agilent overall performance technical specs.
Our columns satisfy superior design requirements, Consequently guaranteeing performance and scalability. DAC know-how enables reproducibility and robustness as time passes.
The level of sensitivity demanded will depend on the focus on the analyte and more info the applying. Sensitivity needs to be viewed as also in scenarios of analyses operate in compliance with Formal techniques or restrictions.
Bottom line, the click here selection of detector depends on the nature on the analyte, the expected sensitivity, and also the analytical purpose. Obtain this guideline to obtain a comprehensive explanation on the widespread types of detectors used in HPLC.
The photodiode array (PDA) gets its identify from the fact that the grating could spread the spectrum throughout an assortment of photodiodes.
Given the infinite amount of compounds and structural diversity of potential analytes, HPLC is never a a single-dimension-suits-all approach. From nano to preparative scale separations, Here's a listing of the most common types of HPLC techniques and when to use Just about every.
Retention time – time among sample injection and the utmost peak sign of your analyte within a chromatogram
