Asenapine maleate method of analysis by HPLC?
yes
What is rs-hplc?
"RS-HPLC method" means "Related Substance HPLC Method".
What is assay by HPLC?
HPLC is high-performance liquid chromatography. This method is used for the separation and production of chemicals but also for chemical analysis.
What is mean by delay volume in HPLC analysis?

Why reproducibility is important in hplc?
This instrument plays an important part in analysis of materials. Without a good reproducibility the machine would be of little value.
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
Why does a sample in HPLC analysis need to be heated?
Most often it doesn't. Are you thinking about gas chromatography? I have used HPLC at room temperature for reversed phase analysis of organics and I have used it at 4 degrees C for protein purification. Only once have I done any at elevated temperature. Gas chromatography uses gas-liquid partitioning though and is almost always done at higher temperatures.
