Agilent-Accredited support specialists can be found around the world and sustain a listing of authentic Agilent areas. They’ll immediately diagnose your system onsite and execute any required repairs—ordinarily in just one stop by.
There are four different types of HPLC columns used in analysis, depending upon the study. Keep on reading To find out more.
The Agilent rep was capable to prioritize our services ask for and be onsite six days before when compared to the quoted provider date.

Reverse section columns are used in reverse stage chromatography, in the event the stationary stage is significantly less polar in comparison to the cellular section. Put simply, the reverse of usual phase chromatography.
The stationary section is actually a granular material with quite small porous particles in a separation column.
Chemical character: Polarity, hydrophobicity, and demand of one's analytes will impact their interaction While using the stationary section.
As an example, C18 is often used to different peptides or little molecules, although C4 is best for proteins. Selectivity includes a increased effect on resolution than particle measurement.
Numerous other detectors are actually used in HPLC. Measuring a alter during the mobile period’s refractive index is analogous to checking the mobile section’s thermal conductivity in fuel chromatography. A refractive index detector is website sort of universal, responding to Nearly all compounds, but has a relatively weak detection Restrict of 0.
Be sure to verify you prefer to to obtain marketing and advertising e mail messages about Thermo Fisher Scientific services and products.
Will allow simultaneous and ongoing Procedure of up to three chromatography separations. These may be Section of a batch and/or multi-column method
This variance is monitored as being a kind of an electronic signal. There are actually different types of detectors accessible.
