Summary
High-performance liquid chromatography (HPLC) efficiently separates IgG and albumin, and accurately determines blood theophylline and serum uric acid levels. This method shows strong correlation with established techniques for clinical laboratory testing.
Area of Science:
- Analytical Chemistry
- Biochemistry
Context:
- High-performance liquid chromatography (HPLC) is a standard technique in clinical laboratories due to its reproducibility and automation.
- Accurate quantification of specific biomarkers is crucial for disease diagnosis and monitoring.
Purpose:
- To demonstrate the application of HPLC for the separation of IgG and albumin from commercial preparations.
- To validate HPLC for the determination of blood theophylline levels.
- To assess HPLC for the precise measurement of serum uric acid concentrations.
Summary:
- HPLC successfully separated IgG and albumin within 10 minutes using a TSK gel G 3,000 SWXL column.
- Automated HPLC determination of blood theophylline showed good correlation with the Enzyme Immunoassay (EIA) method.
- Serum uric acid was accurately measured by HPLC after acid deproteinization and optimized eluent conditions (pH 2.2) for a TSK gel ODS-80 TM column, correlating well with the uricase-catalase method.

01:13Principles Of Column Chromatography
The chromatography technique was first invented in 1901 by Michael S. Tswett, a Russian botanist, to separate plant pigments using organic solvents. Further, in 1941, Archer John Porter Martin and R. L. M. Synge modified the technique by packing silica gel into a column. A mixture of amino acids was then separated on the packed column using chloroform and water mixture as the mobile phase. This was the first report on column chromatography. At present, column chromatography is a widely used...
01:29Types Of Column Chromatography
The stability and compatibility of column material with samples are crucial for efficient purification in chromatographic techniques. Various operating parameters such as pH, temperature, or solvent affect the packing of the column material, thereby determining the purification efficiency. The choice of column material also plays an essential role in deciding the operating parameters and can be modified based on the proteins that need to be purified.

01:11High-Performance Liquid Chromatography: Introduction
High-performance liquid chromatography(HPLC), formerly referred to as High-pressure liquid chromatography, is a powerful technique used to separate, identify, and quantify components in complex mixtures. The term "high pressure" refers to using high pressure to push the liquid mobile phase through the tightly packed columns.
In HPLC, two phases play a critical role in the separation process:

01:05High-Performance Liquid Chromatography: Elution Process
In High-Performance Liquid Chromatography (HPLC), the elution process is critical to the separation of analytes and the quality of chromatographic results. Elution describes how compounds move through the column and separate based on their interactions with the mobile and stationary phases. This process determines the resolution, peak shape, and retention times in the chromatogram, which are essential for identifying and quantifying components in complex mixtures. Understanding the elution...
00:57High-Performance Liquid Chromatography: Instrumentation
High-performance liquid chromatography, or HPLC, is an analytical technique that separates liquid samples under high pressures. An HPLC instrument consists of glass bottles for storing solvents called mobile phase reservoirs. HPLC-grade solvents are used to maintain high purity, and the dissolved gases are removed using a degasser, such as a vacuum pumping system or sparging with helium. The solvents are then pumped into the analytical column using a screw-driven syringe or reciprocating pumps.
01:15High-Performance Liquid Chromatography: Types of Detectors
The role of the detectors in High-Performance Liquid Chromatography (HPLC) is to analyze the solutes as they exit from the chromatographic column. The detector recognizes the solute's property and generates corresponding electrical signals, which are converted into a readable graph of the detector's response versus elution time called a chromatogram at the computer. There are several types of HPLC detectors, each with its own advantages and limitations, depending on the analyte properties and...
