Chromatography Essay Examples

Phytoconstituents are defined as the chemical compounds that can be found naturally in plants where the word phyto means “plant” in Greek. Isolation and purification of phytoconstituents is the most difficult and complex operation in phytopharmaceutical research. Plant extracts are complex mixtures which contain hundreds...

Chromatography is the best technique for identifying different chemicals within a mixture. Rationale Forensic chemistry is the application of chemistry, forensic toxicology, in a legal setting. A forensic chemist can assist in the identification of unknown materials found at a crime scene. Forensic Chemists have...

Introduction Forensic investigations: defined by applications of principles to matter (Merriam, 2019). Examined through analytical techniques; procedures for analysis of facts, issues, or status- generally are tasked and time-limited (ManagementMania, 2016). However, with increased effectiveness- accuracy of findings will intensify and limitations will decrease. Chromatography...

Introduction The multi-exposure to various mycotoxins may lead to additive, synergic or antagonist toxic effects (Ficheux et al, 2012) to humans and animals. This may cause chronic and acute diseases thereby calling for food safety measures. Many countries have setup strict regulations for mycotoxin control...

Analysis High Performance Liquid Chromatography (HPLC) with the Pre-Column Fluorescence Derivatization is a method in which the separation and ultra-sensitive detection of a substances occur. This sensitive method simultaneously detects eight amino acids (AAs); glycine, alanine, serine, glutamic Acid, arginine, tyrosine, phenylalanine, and tryptophan. These...

ABSTRACT High-performance liquid chromatography (HPLC) is a chromatographic process used in the fields of analytical chemistry, biochemistry and industrial separation of a mixture of compounds. The key objectives for using HPLC are the detection, quantification and purification of the mixture’s specific components.HPLC plays an important...

Introduction According to Giddings and Keller (2016), chromatography is a technique used to separate solutes from a mixture. It is widely used for separation and identification of biological compounds, or to analyse mixtures. An example of its use is separation of pigments from dyes. Identification...

INTRODUCTION Food analysis is a very important branch of analytical chemistry which provides data about chemical composition of food stuffs, contaminants and ensures safety of foods during import and exports. Many compounds which are found in nature, can be chiral which may have one or...

Chromatography is an important physical technique that is used for separation, identification, and purification of multi-component mixtures for qualitative and quantitative analysis (Coskun, 2016). There are many types of chromatographic systems such as liquid chromatography, which began in the late 1930s (Guiochon, Felinger, Shirazi and...

Chromatography is used to distinguish various components from product mixtures. All types of chromatography have a stationary phase (a solid or a solid-based liquid) and a mobile phase (a liquid or a gas). The mobile phase moves through the stationary phase. Distribution of analyte takes...
