Which one is advanced gc or hplc?
HPLC is advanced
What is the deference between GC and GCHS?
What is deference GC, HPLC & GCHS
How do you use resolution factor in HPLC?
resolution factor
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).
What is C8 and C18?
HPLC columns. (HPLC - High Performance Liquid Chromatography.)
Which one is advanced gc or hplc?
HPLC is advanced
What is the deference between GC and GCHS?
What is deference GC, HPLC & GCHS
Why volatile compounds are analysed in gc but not in hplc?
GC can give very resolved sharp peaks with short run time compared to hplc. additionally, there is less compatibility issue in setting an MS up to a GC than HPLC
What is Cut time in HPLC or GC?
10 - 15 minutes
How does HPLC complement GC in the analysis environmental products?
i have no answer for it...think yurself...
What analytic method is more preferrable betwee GC and HPLC?
Whether GC or HPLC is a more preferable analytical method depends on the material being analyzed for, the likely concentration in which it is found, and what medium it may be in/on (water, oil, different kinds of filters, etc.) There is no single, universally applicable answer.
What kind of species can be separated by high performance liquid chromatography but not gas chromatography?
HPLC can separate nonvolatile species and GC cannot.
How do you use resolution factor in HPLC?
resolution factor
What does medical code 82542 stand for?
CPT Code 82542- Column chromatography/mass spectrometry (eg, GC/MS, or HPLC/MS), analyte not elsewhere specified; quantitative, single stationary and mobile phase.

What is difference between gc and hplc?
gas chromatographt (GC) and High Performance Liquid Chromatography (HPLC) are different , and to understand why you must think about what chromatography is: Chromatography in its simplest form is like putting ink on blotting paper and watching the colours separate. Liquid chromatoraphy uses a "column" which is made from bare or bonded silica, it separates a mixture of compounds by how polar they are. You can use a gradient of different solvents. GC also uses a column, but it is a capillary column and instead of using a liquid to carry your mixture which needs to be separated it uses a carrier gas, like nitrogen. You can vary the temperatures in both LC and GC to aid better resolution. GC is used for more volatile compounds and LC is used more less volatile. HPLC usually refers to reversed phase, normal phase is where the column is vare silica which is very polar. Bonded silica is bonded with hydrocarbons which is non polar. The thing to remember is that "like attracts like" so if the column in non polar, the compound to elute first will be the most polar. To summarise, they are both separation techniques, one uses gas and the other liquid. You would choose which one to uese depending on how volatile the compounds which you want to separate are.

Peak-to-valley ratio in HPLC?
to calculate signal to noise use this formulae peak hight *2/noise level
