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
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.
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.
Retention time in High Performance Liquid Chromatography (HPLC) refers to the time it takes for a compound to travel through the chromatography column and elute from the detector. It is a key parameter for identifying and characterizing compounds in a sample. Retention time is influenced by factors such as the column type, mobile phase composition, and compound properties.

i have no answer for it...think yurself...
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.

why RT was shifting & how to RT calculation in HPLC
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.
In HPLC RRT means Relative Retention Time and RRF is Relative Response Factor

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).
