In HPLC (High-Performance Liquid Chromatography), needle wash and seal wash refer to specific cleaning protocols for the injection system. The needle wash typically involves rinsing the sample needle with a solvent to prevent cross-contamination between samples, ensuring accuracy and reproducibility. Seal wash, on the other hand, involves cleaning the area around the injection port seal to maintain proper sealing and prevent sample leakage or contamination. Both processes are essential for maintaining the integrity of the analysis and prolonging the lifespan of the equipment.

What is seal wash in high pressure liquid chromatography?
A seal wash in high pressure liquid chromatography (HPLC) involves flushing solvent through the seals of the pump to prevent contamination and deterioration of the seals over time. This helps maintain the integrity of the pump and prevents leakage, ensuring accurate and consistent results during sample analysis.
What kind of injection use the Z-track to seal the needle tract?
intramuscular
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 the first step you should take after a needle stick?
wash the area with soap and water
Retention time calculation for hplc?
why RT was shifting & how to RT calculation in HPLC
How does a needle pass through a balloon without popping it?
A needle can pass through a balloon without popping it because the rubber of the balloon is stretchy and can temporarily seal around the needle, preventing air from escaping and causing the balloon to pop.
What type of species can be separated by HPLC but not by gas liquid chromatography?
mixture of enantiomers can be separated by HPLC
What is rs-hplc?
"RS-HPLC method" means "Related Substance HPLC Method".
Where can one purchase HPLC detectors?
You can purchase used HPLC detectors and other equipment from the usedhplc website or from the ebay bidding website. Alternatively you can buy HPLC detectors from the equipnet website.
What is RRT and RRF in hplc?
In HPLC RRT means Relative Retention Time and RRF is Relative Response Factor
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.
What are the key differences between normal phase HPLC and reverse phase HPLC in terms of their separation mechanisms and applications?
Normal phase HPLC separates compounds based on their polarity, with the stationary phase being polar and the mobile phase being nonpolar. Reverse phase HPLC separates compounds based on their hydrophobicity, with the stationary phase being nonpolar and the mobile phase being polar. Normal phase HPLC is typically used for separating polar compounds, while reverse phase HPLC is used for separating nonpolar compounds.
