How do you distinguised np-hplc and rp-hplc?
NP-HPLC is "Normal Phase" HPLC, wherein the solvents used are less polar than the substrate in the HPLC column (e.g. using hexane or dichloromethane with a silica HPLC column). RP-HPLC is "Reverse-Phase" HPLC, wherein the solvents used are more polar than the substrate in the HPLC column (e.g. using Water and Methanol with a octadecylsilane (ODS or C18) column).
Which one is advanced gc or hplc?
HPLC is advanced
What is C8 and C18?
HPLC columns. (HPLC - High Performance Liquid Chromatography.)
Definition of standard in HPLC?
Answer: HPLC standards are an indispensible tool for analytical HPLC applications. They are used to monitor column performance & calibrate detector response.
What is difference bet GLC and HPLC?
GLC has a stationary liquid phase and gas moving phase HPLC had a stationary solid phase and liquid moving phase HPLC is done under high pressure. HPLC can be used for thermally unstable compounds as opposed to GLC HPLC can be used for polar or low volatile compounds as opposed to GLC
Is it true that only reproducibility is important when making scientific measurements?
NO. But, if you can't reproduce it, it ain't science.
How pH play an important role in hplc sepration?
depending on pH resolution is there
What does the reproducibility of data refer to?
the reproducibility refers to how close a group of measurements are to each other
What is the difference between reproducibility and accuracy?
Accuract is how accurate you are at somehting and rreproducibility is how reproducibility you are at something.

What a measurenment that depends on its reproducibility?
Precision.
Retention time calculation for hplc?
why RT was shifting & how to RT calculation in HPLC

Why is it important to establish the reproducibility of data?
By telling others what you learned keeps science going. Then other scientists can then conduct their own tests based on your resuts.
Definition of reproducibility?
the ability to be reproduced or copied.
