High-Performance Liquid Chromatography (HPLC) HPLC is a highly precise method for separating and quantifying individual pigments. ...
Oligonucleotides are typically composed of short-chain nucleotides (deoxyribonucleotides or ribonucleotides) of less than 20, serving as short RNA and DNA oligomers. They can be used as probes to determine the structure of DNA or RNA, and are used in processes such as gene chips, electrophoresis, and fluorescence in situ hybridization.Oligonucleotides are widely used in biology, agriculture, ...
Phosphorylation is one of the most common and important post-translational modifications of proteins, playing a key role in many cellular activities such as signal transduction, cell division, metabolic regulation, and cell death. Therefore, the accurate identification of the phosphorylation status of proteins is crucial for understanding cellular functions and disease mechanisms. 4D-label-free ...
Purification: Purify the synthesized peptide by reverse-phase high-performance liquid chromatography (HPLC) using a suitable solvent system and detect the peptide using UV absorption at 214 nm. 9. ...
The resulting peptides are acidified, and a biphasic system is formed by mixing with ethyl acetate. The aqueous phase, containing the peptides, is collected, dried, and resuspended for further analysis. LC-MS/MS Analysis The MWCO-desalted peptide mixture is resuspended in formic acid solution and injected into an HPLC system coupled to a mass ...
To ensure long term reliability and efficiency of the SCION Instruments LC6000 it is vital that considerations are taken when operating the HPLC system. SCION Instruments have now released their LC6000 Good Practice Handbook, a necessity for any HPLC user. The following handbook will provide guidelines for instrument preparation and routine ...
It is essential for Chromatographic Analysis, including high-performance liquid chromatography (HPLC), gas chromatography (GC), ion chromatography (IC), supercritical fluid chromatography (SFC), and capillary electrophoresis (CE), ultra-high performance liquid chromatography (UHPLC), tandem techniques such as GC-GC, GC-MS, LC-GC, LC-MS, which constitutes a major portion of ...
High performance liquid chromatography (HPLC) has become an essential technique in pharmaceutical analysis for the separation, identification, and quantification of pharmaceuticals. ...
What is HPLC technology? High performance liquid chromatography (HPLC) is also called "high-speed liquid chromatography", "high-resolution liquid chromatography", "modern column chromatography" and so on. ...
In addition to fume hoods, rotary evaporators, and glassware, we are able to use major equipment including a Bruker Avance 300 MHz NMR spectrometer, Agilent 1100 LCMS, preparative HPLC systems, automatic flash chromatography system, hydrogenator, and ozone ...

Product descriptionStainless Steel Capillary Tube Description:Whether you need to exchange device tubing as a section of your troubleshooting or want to minimize the dwell extent of your system as you pass to narrower columns. As one of the most professional stainless steel capillary tube suppliers in China, WENZHOU HUASHANG STEEL CO., LTD. has the first-rate tubing in the ...
It can control up to four independent chromatography systems at a time and has available connection methods to the majority of HPLC systems. ...
A user needs to know more about the systems and proper comparison of these technologies. In some cases is difficult to understand what are the fundamental differences between the pumps that a scientist can found in the laboratory. ...
Will the same approach work for Waters or Agilent or other vendor’s HPLC systems? The best way to measure dwell volume is use a strong solvent that is spiked with a UV absorbing material and to run a gradient from 0% to 100% over 10-20 minutes. ...
When you login to Empower, you select a project to work in and a chromatographic system (HPLC, GC) to use for data acquisition (Figure 1). Figure 1 The interface opens and we see the navigation bar on the left which will guide us through the software (Figure 2). ...
Here are my tips/best practices for column and HPLC/UHPC/UPLC system maintenance. Maintaining your LC columns Proper storage of HPLC columns will increase longevity and performance. ...
An analytical method based on the HPLC (high performance liquid chromatography) system was used for TNT detection. ...
Unfortunately, we are not able to provide a published limit for every column that we produce, but here are a few of them that we have specified: For 3 and 5 um fully porous particle ROC LC columns, the maximum operating pressure is 400 Bar/ 5800 psi, which is also the limit for older or more conventional HPLC systems and close to the limit for column hardware. ...
