Liquid Chromatography can be achieved through many methods including reverse-phase and hydrophilic interaction liquid chromatography (HILIC). Liquid chromatography is a form of column chromatography that uses an HPLC pump to pump an analyte in a solvent (the mobile phase) at high pressure through a column (stationary phase) to separate...
Vials and 96-well plates are standard consumables used in chromatography. While vials were previously the industry standard, well plates have become more popular in recent decades. Both vials and well plates still hold advantages that make them viable options in chromatography processes. Vials vs. 96-well plates for chromatography is a debate worth investigating before deciding which to use in your lab.
Chromatography is a vital tool used in many industries to determine the composition of a mixture. Chromatography is widely known for its role in scientific research, although it holds importance in other industries. Chromatography plays a vital role in industries we interact with quite often. Pharmaceuticals, clinical trials, environmental and chemical safety, food and beverage, drug testing, forensics, petroleum creation, and molecular biology are some of the most common uses of chromatography.
The COVID-19 pandemic has created unprecedented struggles across the world due to symptom variability and high spread rate. As COVID-19 continues to surge through the U.S., there is an increasing need for technology that will help us understand viruses like COVID-19 faster.
Reliable and accurate results for pesticide and mycotoxin testing is of utmost importance for the safety of people consuming cannabis-derived products such as cannabis brownies and other edibles. Edibles are one of the most popular categories of consumption of cannabis-based products, and brownies are one of the most commonly consumed edible. Brownies contain high levels of potential interferences (carbohydrates and fats), so methods developed for this application will be a great starting point for similar matrices.
As many laboratories continue to experience drastic budget cuts, lab managers are tasked with difficult decisions on how they can spend less money without sacrificing throughput and accuracy of results. Chrom Tech offers high quality chromatography vials at an affordable price. As touched on in a previous blog article, Chrom Tech is now offering limited volume inserts pre-loaded into autosampler vials to reduce labor time and costs for your laboratory while maintaining fair and competitive prices on the vials.
The COVID-19 pandemic has affected laboratories in many ways, including many cutting the number of employees in the laboratory at any given time. Spreading the virus is a main concern across workplaces, and eliminating unnecessary touch points between employees is more important now than it has ever been. An inhouse stand alone gas generator reduces the number of personnel contact involved with the use of gas bottles and cylinders in the laboratory. Once a generator is installed in the laboratory, minimum user interaction is required for 24/7 usage, and minimal maintenance is required.
The coronavirus pandemic continues to cause shortages on hand sanitizers as people are doing their part to prevent the spread of COVID-19. Hand sanitizers are hard for consumers to find, but some companies with laboratories equipped for laboratory testing are stepping up to help meet the demands by using their isopropanol and ethanol to make sanitizer.
The current economic situation revolving around the COVID-19 pandemic will continue to create lasting effects on our economy. Chrom Tech is working to support our customers throughout and beyond the COVID-19 situation.

Laboratories across the world are responsible for quickly and accurately reporting research results. According to the CDC, 70% of medical decisions made depend on test results from a laboratory. An inefficient laboratory can cause unnecessary expenses, but also delay research and results and even have detrimental effects on patients.
Whether analyzing for drugs, forensic evidence, or specific compounds in a specific clinical matrix, accurate sample analysis is important. For example, as the American Chemical Society discusses, “The credibility of the legal system critically depends on forensic tests that are consistent, accurate, and scientifically valid.” If a sample is analyzed inaccurately, serious consequences may occur so it is important that precautions are taken to eliminate margins of error in every step of the analysis.
As the Cannabis industry grows in the United States, laboratories are required to follow challenging sample preparation and analysis procedures to accurately measure active compounds, according to Cannabis Science and Technology. The accuracy of the sample preparation phase is extremely important, and variability between analysts can be very problematic for laboratories with a manual dilution process. Using the Microlab 600 can reduce the %RSD by more than 50% when compared to hand pipetting.
Chrom Tech is constantly working to make shopping easier for consumers. Replacing the various capillary tubing connections in your HPLC can be intimidating and confusing. In our latest efforts, we put together a capillary replacement guide for your standard Agilent HPLC systems.
As women and men age, many face issues that can be treated by hormone replacement therapy, according to the Women’s Healthcare Associates. However, hormone steroids are metabolized differently from person to person, which leads to complexity in treating a patient effectively without increasing a person’s risk for diseases such as cancer, dementia, and loss of bone density. It is important for researchers to be able to quantitatively determine endogenous steroid levels in order to monitor patient health and success with the hormone replacement therapies.
Cannabis products have been marketed as a natural cure-all, leading way to CBD oils, creams, pills, and even gummies that can be found all over stores and marketplaces in America today.
