HPLC (high-performance liquid chromatography) uses a UV-visible lamp for detection, often for compounds that absorb light in the UV-vis range. GC (gas chromatography) does not typically use a lamp for detection; it often uses a flame ionization detector (FID) or other detectors that do not rely on a lamp for operation.
What else can I help you with?
Which one is advanced gc or hplc?
HPLC (High-performance liquid chromatography) is generally considered more advanced than GC (Gas chromatography) due to its broader application range, higher sensitivity, and ability to separate a wider range of compounds. HPLC is often preferred for analyzing complex mixtures and compounds that are not volatile.
What is the deference between GC and GCHS?
GC typically stands for "Guidance Counselor," referring to a professional who provides students with academic, career, and personal support. GCHS typically stands for "Guidance Counselor in a High School," specifying that the counselor works within a high school setting.
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).
How do you calculate concentration from peak area in HPLC analysis?
To calculate concentration from peak area in HPLC analysis, you can use the formula: Concentration Peak Area / (Slope x Injection Volume). The peak area is obtained from the chromatogram, the slope is the calibration curve slope, and the injection volume is the volume of the sample injected into the HPLC system.
Can you use a C18 column for HPLC with fluorescence detector and methanol as the mobile phase?
Yes, you can use a C18 column and methanol as a mobile phase with fluorescence detector. Fluorescence detector is generally used as it can detect the presence of compounds at a very low concentration.
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
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 is the deference between GC and GCHS?
GC typically stands for "Guidance Counselor," referring to a professional who provides students with academic, career, and personal support. GCHS typically stands for "Guidance Counselor in a High School," specifying that the counselor works within a high school setting.
What is Cut time in HPLC or GC?
Cut time in HPLC or GC refers to the duration of time set for collecting a specific part of the chromatographic peak. It is typically used when only a particular portion of the peak is of interest for further analysis, allowing for precise collection of that specific component. Cut time ensures efficient sample separation and accurate quantification of the targeted analyte.
Can GC and HPLC instruments be used in same room?
Yes, GC (Gas Chromatography) and HPLC (High Performance Liquid Chromatography) instruments can be used in the same room, as long as certain precautions are taken to prevent interference between the two instruments. This includes proper ventilation to avoid cross-contamination, proper spacing between the instruments to prevent vibrations or electromagnetic interference, and ensuring that the room meets the specific requirements for each instrument.
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.
