GLC is basically the same as HPLC except GLC is done with a liquid stationary phase and gaseous mobile phase. HPLC has a solid stationary phase and liquid mobile phase.
So your sample in GLC is a gas...this means you either have to heat it or it has to be volatile. Which is problematic as heat tends to destroy things (especially not good if you're using GLC to find out what your sample is...) and of course not everything is volatile.
Meanwhile, HPLC has neither of these problems.

What is Difference Between HPLC UV detector Spectrophotometer uv detector?
HPLC UV detector is a component used in high-performance liquid chromatography (HPLC) to monitor eluent absorbance, while a spectrophotometer UV detector is a standalone instrument used to measure the absorption of light at different wavelengths. HPLC UV detectors are specifically tailored for chromatography applications, whereas spectrophotometer UV detectors are more versatile and used for various analytical purposes.
What are the differences between reverse phase HPLC and normal phase chromatography techniques?
Reverse phase HPLC and normal phase chromatography are two types of chromatography techniques that differ in the polarity of the stationary phase and mobile phase. In reverse phase HPLC, the stationary phase is non-polar and the mobile phase is polar, while in normal phase chromatography, the stationary phase is polar and the mobile phase is non-polar. This difference in polarity affects the separation of compounds based on their interactions with the stationary phase, leading to different retention times and selectivity in each technique.
What are the key differences between HPLC reverse phase and normal phase chromatography techniques?
In reverse phase HPLC, the stationary phase is nonpolar and the mobile phase is polar, while in normal phase HPLC, the stationary phase is polar and the mobile phase is nonpolar. This difference in polarity affects how compounds interact with the stationary phase, leading to variations in separation and elution times.
What does HPLC stand for?
HPLC stands for High Performance Liquid Chromatography. It is a technique used to separate and analyze components in a liquid mixture based on their interactions with a stationary phase.
What are the key differences between HPLC normal phase and reverse phase chromatography techniques?
In normal phase HPLC, the stationary phase is polar and the mobile phase is nonpolar, while in reverse phase HPLC, the stationary phase is nonpolar and the mobile phase is polar. This difference in polarity affects how compounds interact with the stationary phase, leading to different separation mechanisms and selectivity in each technique.
What is difference between high pressure liquid chromatography and high performance lequid chromatography?
High pressure liquid chromatography (HPLC) and high performance liquid chromatography (HPLC) are often used interchangeably. HPLC refers to modern liquid chromatography systems with high resolution and efficiency, while high pressure liquid chromatography specifically highlights the use of higher pressures in the system to improve separation and speed. Both terms generally refer to the same chromatographic technique.

What difference between dad and uv detector in hplc?
Liquid chromatography (LC) encompasses all chromatographic techniques using liquid mobile phase, including planar chromatography (paper chromatography and thin-layer chromatography) and column chromatography (classical column chromatography, and high-performance liquid chromatography on packed and capillary columns). The term liquid chromatography is nowadays often used as a sinonim for high performance liquid chromatography (HPLC) and ultra-high performance liquid chromatography (UHPLC).
What type of species can be separated by HPLC but not by gas liquid chromatography?
mixture of enantiomers can be separated by HPLC

Why is hplc known as high performance liquid chromatography?
due to its reproducibilityt
What are the key differences between FPLC and HPLC, and how do these differences impact their respective applications in chromatography?
FPLC (fast protein liquid chromatography) and HPLC (high-performance liquid chromatography) are both chromatography techniques used to separate and analyze compounds. The key differences lie in their intended applications and the types of samples they are best suited for. FPLC is primarily used for purifying proteins and other biomolecules, while HPLC is more versatile and can be used for a wider range of compounds including small molecules, peptides, and proteins. FPLC typically operates at lower pressures and flow rates compared to HPLC, making it gentler on biomolecules. These differences impact their applications in chromatography by determining which type of sample each technique is best suited for. FPLC is ideal for purifying proteins and biomolecules, while HPLC is better suited for a broader range of compounds. The choice between FPLC and HPLC depends on the specific requirements of the experiment and the nature of the sample being analyzed.
What does HPLC stand for?
HPLC stands for High Performance Liquid Chromatography. It is a technique used to separate and analyze components in a liquid mixture based on their interactions with a stationary phase.
What are the key differences between HPLC normal phase and reverse phase chromatography techniques?
In normal phase HPLC, the stationary phase is polar and the mobile phase is nonpolar, while in reverse phase HPLC, the stationary phase is nonpolar and the mobile phase is polar. This difference in polarity affects how compounds interact with the stationary phase, leading to different separation mechanisms and selectivity in each technique.
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 dead volume HPLC?
The dead volume in HPLC is 137.45. The dead volume in science is used in retention measurements and also in thermodynamic studies and the abbreviation HPLC stands for High Pressure Liquid Chromatography.
