Gas Chromatography(GC) Column Selection Guide

Gas chromatography(GC) is a simple, fast, efficient and sensitive modern separation and analysis technology, which is widely used in scientific research and inspection departments such as environment, medicine, chemistry and chemical industry, and it is also an indispensable detection method for the determination of pesticide residues. Gas chromatograph has the advantages of fast analysis speed, high separation efficiency, high sensitivity, high selectivity, etc. However, due to the complexity of the sample matrix, operator error, and the instrument itself during the analysis process, the gas chromatograph will have various problems, which will affect the results of chromatographic analysis.  Thus, it is critical to have in-depth understanding of the common solutions for gas phase analysis.

OEM Custom Solutions for Vaccine Aseptic Filling in Vial Filling Machines

To fight against COVID-19, many pharmaceutical giants, including Pfizer-BioNTeh, Moderna, Janssen (J&J) and Merck, have been pushing to produce more and more doses of vaccine. However, the manufacturing process of vaccine is very complex, especially mRNA vaccines that are a new type of vaccine to protect against infectious diseases. Another challenge is how to fill thousands and thousands of small vials with desired volumes.  We work with vial filling machine manufacturers to develop fully automatic vaccine dosing system to inject and fill vials with high accuracy, precision and efficiency to ensure volumetric consistency of the dispensed vaccine.  The vial filling machine is a complex mechatronic system and must be held to cGMP and US FDA regulations to allow their use in sterile environments.

Weltch HPLC Columns List in PQRI & USP Chromatographic Database

The Product Quality Research Institute (PQRI) was established in 1999, and brings together members of the pharmaceutical industry, academia and regulatory agencies to develop science-based approaches to regulation. The PQRI column database was created for scientists to find similar HPLC columns that can replace the original column for their works. PQRI approach for selecting columns of equivalent selectivity is based on five column properties (hydrophobicity “H”; Column steric interaction “S”; Column hydrogen-bond acidity “A”; Column hydrogen-bond basicity “B”; Column ion-exchange capacity “C”).  Welch has 19 column phases from 3 categories ( Xtimate, Ultisil and Topsil) listed in this database ( see Table 1). In this database, one enters the original column and the database will list similar columns of equivalent selectivity.  

Peristaltic Pump Tubing Selection Guide

Peristaltic pumps are typically used to pump sterile or aggressive fluids without exposing those fluids to contamination from exposed pump components. They are self-priming, reversible and highly reliable.  Also, peristaltic pumps are suitable for applications where isolation of the product from environment is critical, such as pumping abrasives, corrosive or/and viscous fluids.  There are a wide variety of applications of peristaltic pumps listed but not limited:  Medicine:  Dialysis machine/medical infusion pumps, blood transfusion ; Testing and research: Auto-analyzer , analytical chemistry experiments, media dispensers;  Chemical handling: Pharmaceutical production, dosing systems etc. 

HPLC Column Selection Guide

Chromatography is a laboratory technique commonly used for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase. Column chromatography is a separation technique in which the stationary bed is within a tube.  Thus, the column used in this analytical method is the heart of the chromatographic system.  Common requirements for columns include high column efficiency, good selectivity and fast analysis speed etc.  Packing materials for HPLC are mainly all porous spherical silica gel, organic polymer matrix or core-shell silica gel. Their particle sizes, for instance, 1.8 µm, 3 µm, 5 µm, 7 µm and 10 µm are available. The selection of columns,  and classification and main features of packaging materials are described herein.

Fiber Optics Solutions for Air Sensitive Materials Analysis in Glove Box

Air sensitive materials such as metal hydrides, metal halides, metal alkyls and aryls, metalloids have applications in a number of chemical processes,  such as certain catalysts, OLED (organic light-emitting diode) applications, inert gas welding, lithium-ion battery applications, and semiconductors.  Because these materials can react, oxidize, or even explode when exposing to oxygen and moisture, it is critical to isolate them in an air-free environment.  For example, glove boxes filled or purged with an inert gas such as nitrogen or argon gas offer a sealed environment that allows users to manipulate or handle these air sensitive materials (Figure 1).  Both chemicals and equipment can be transferred in and out via the antechamber. 

Key words: Air-sensitive; fiber optic; glove box; spectroscopy; analytical chemistry
