Types of High-Performance Liquid Chromatography (HPLC) Columns: A Review

FoodTech: Jurnal Teknologi Pangan

Some chemical analysts, especially those working in the food sector, often find it difficult to choose the HPLC columns for their research. Every so often they tend to modify their method to fit whatever HPLC column available in their laboratory instead of looking for the column type best suited to their experiments. Other than that, HPLC column types are often very limited discussed in the class. This is particularly disadvantageous for those who have sufficient access to select the HPLC column they need for the best result. The lack of insight into the types of HPLC columns available in the market also influenced their decision to select the right column in their analysis to a large extent. This article briefly reviews the differences between the commonly used Particle-Packed Columns with the newer yet less frequently used Monolithic Columns. The types of HPLC columns based on polarity, molecular size, and the electrical charge will be described further, along with the working pri...

Mehrdimensionale hochleistungsflüssigkeitschromatographische - gaschromatographische (HPLC-GC) Kopplungstechniken für die Lebensmittelanalytik in Routineumgebungen

2016

Routine monitoring of foodstuffs is an important instrument for consumer protection. Understandably, fast and robust analysis methods are necessary to cope with the modern nutritional habits of the fast-growing population. In contrast, the chemical complexity and variety of foodstuffs are challenges complicating the development of such analytical methods. Nevertheless, routine laboratories faced with thousands of samples per year need to be able to identify harmful substances and quality mismatches in a short time span. Chromatographic methods are omnipresent in the field of food science. They are used throughout the whole analytical process either for sample preparation or for analyte separation. However, online hyphenation of sample preparation with the separation and detection processes is so far rarely observed in routine environments. Hyphenation of liquid and gas chromatographic techniques (LC-GC), for example, provides an efficient and fast sample preparation online coupled t...
