Analytical Standards Guide

What is Chromatography Chromatography is the most commonly applied method for the separation of substance mixtures into single components. This powerful technique is for example used in quality control of drugs, in clinical research, or trace analysis of harmful substances. Chromatography is essential for analytical chemistry around the world.  Symtera Analytics has a comprehensive range of chromatography products from sample preparation to subsequent analysis. Provides scientists with the best solution for each analytical task. In HPLC we provide powerful solutions featuring pre-packed columns with many different selectivities.  Column Chromatography It is a chromatography technique in which separation is carried out in columns. The column is filled with the stationary phase which can either be silica, alumina, or cellulose. The bottom of the column is packed with cotton or glass wool to support the stationary phase. The column preparation is usually carried out by two m

  Laboratory reagents have a multitude of functions when it comes to chemical reactions or processes. The purpose generally is to initiate a chemical reaction between the reactants while not being part of the formation of the product itself. Sometimes reagents are also used to determine if a certain product is produced, they can be of many forms and structures. Some types of reagents are pure substances and some are compounds or mixtures. They usually come in the form of inorganic chemicals and are sometimes made of organic molecular structures. Some reagents can be used for multiple kinds of reactions while others tend to be specific and serve their purpose for a certain reaction only. Following are types of lab reagents that are commonly used in laboratories. Hydrochloric Acid This acid is very corrosive and has many industrial purposes. It is commonly used to make PVC pipes and polyurethane . While in lower concentration this reagent is used in leather processing in househo

In this blog, we are going to discuss what's actually going to do in the quality control lab and what kind of analysis is possible? And during analysis why standards are required? What kind of standards you can employ between the analysis? Before diving into deep discussion , the first thing you should know is the type of analysis commonly performed in the quality control laboratory. Type Of Analysis in The Quality Control Laboratory There are two kinds of analysis ·          Qualitative analysis ·          Quantitative analysis Qualitative Analysis Quality analysis when you are characterizing the physical properties of the material or substance. It means you are doing the description test. You are checking the solubility of the material substance. You are identifying the metals by spectroscopy or HPLC. Here you will not get any measurement values. Quantitative Analysis In a quantitative analysis, you will get measurement values like percentage of water content in

  What are Reference Standards? Solutions of exactly known strength are called standard solutions. A standard solution contains a known weight of chemicals in a definite volume of solution. A standard solution is prepared by dissolving an accurately weighed quantity of highly pure substance in a definite volume of solvent. Types of Standard Solutions There are two types of standard solutions first is primary standard and secondary standard. Primary standard Any reagent or chemical which has all these properties is suitable for use as a primary standard: It is extremely pure.  It is highly stable.  It is anhydrous.  It is less hygroscopic.  It has a very high molecular weight.  It can be weighed easily.  It should be ready to use and available .  It should be preferably nontoxic Following is the detail of a few properties Purity: To qualify as being the primary reference standard, a chemical needs to be extremely pure. Preferably, it should have 99.98% of purity. Ther

  The drug reference standard is a standardized substance that's utilized in the pharmaceutical industry as a base of measurement for similar substances where the precise active substances of a new drug are unknown. A reference standard provides a calibrated level of biological effects to compare new preparations of the drug. Analytical drug reference solutions and patient education materials put the best available information into the hands of clinicians and patients. They simply analyze the information regarding dosage, efficacy, interactivity , and allergies, even suggesting alternate therapies as appropriate. Drug reference standards are highly characterized physical specimens used in analytical testing by pharmaceutical and related industries to help ensure the identity strength, quality, potency , and purity of medicines, drugs, biologics, and excipients dietary supplements and food ingredients. All chromatographic reference standards are supplied with a certificate of an
