SFC – Only the Solvent is Critical

Supercritical Fluid Chromatography (SFC) was first developed in the 1960s, using supercritical carbon dioxide and this technology has been commercially available from Agilent for over a decade. Often known for its application to the analysis of chiral compounds, SFC is the ‘greener’ alternative over normal phase separations, further increasing the demand and acceptance of this technology.

This webinar will explain the basic scientific principles of SFC as a highly powerful liquid separation technique for the efficient separation a wide range of analytes. Examples will be given to illustrate, how an SFC system can be coupled to a mass detector to form an integrated LC/MS system to deliver high throughput applications.

 

 What you will learn

•    Similarities and differences between SFC and conventional HPLC
•    Why SFC is the green technique in separation sciences.
•    The advantages of SFC with application examples
•    Theoretical background to SFC
•    How to set up an SFC system with MS detection

Boost your Performance with 2D-LC Separation

This scientific presentation is for analytical chemists, chromatographers, and mass spectrometrists that want to learn, how an additional chromatographic dimension can deliver deeper insights into their samples, particularly when integrated with a mass selective detection system.

Several concepts of the different types of 2D-LC will be explained to enable a comprehensive understanding of this well-established technology.

The benefits of comprehensive Multiple Heart-Cutting, High-Resolution Sampling 2D-LC and the unique technique of Active Solvent Modulation will be explained in detail. Real-life examples will be shown to illustrate the advantages that incorporating an additional separation dimension brings to LC and LC/MS analysis.

 

What you will learn

•    First principles of 2D-LC technology
•    How to configure a mass detector with 2D-LC
•    How 2D-LC technologies enhance the quality of MS detection
•    Where 2D-LC makes a positive difference with several application examples

Customer Stories | Jimmy Woodley

How many GCs can one lab need? In all the years Chemetrix has been supplying top-quality instruments to labs across the country, there’s one customer who surprised us with an ambitious request.

Jimmy Woodley is the now retired lab manager of the chromatography division of Sasol in Secunda. He guided the division through a period of incredible growth and, when he decided to take his team to the next level, he trusted Chemetrix to help equip his lab with Agilent GCs to set them far apart from any other operation in South Africa.

By the time Jimmy retired, his division was working with 160 dual channel GCs and, at a stage, he had over 40 Agilent GCs in a single order. This was a customer relationship that spanned years and Chemetrix had the honour of working with Jimmy and his team to drive the growth of their analysis as well as enhance their capabilities as a laboratory.

Watch Jimmy tell the story in his own words and reflect on a fond relationship with the team at Chemetrix.

Chemetrix Backs Yes 4 Youth

SA Youth is supported by the Presidency, YES, National Youth Development Agency (NYDA) and Harambee Youth Employment Accelerator as part of the Presidential Youth Employment Intervention.

The initiative is explained best by the pledge that we are signatories to.

“Through my company’s participation in the YES initiative, I hereby register my organisation with the Youth Employment Service (RF) NPC (registration number 2017/267641/08). I agree with the CEO pledge, acknowledging the critical role that youth play in shaping our economy and our country. I acknowledge that my participation in the programme is giving youth their first chance at a work opportunity and I undertake, as far as possible, to ensure youth are nurtured and encouraged in their placement.

Together with my organisation I am committed to being a co-creator in a future that works for all South Africans, with an understanding that we are subscribing to the values and philosophy of YES. This is based on humanitarian development and socio-economic principles, in the building of a pathway to guide and empower young unemployed South Africans into economic participation. Given the scale and implications of South Africa’s youth unemployment situation, the country and YES must succeed together.”

Chemetrix believes that, through our participation in this program, we are doing our bit however small it may be, to be better corporate citizens. Through this program Chemetrix has an opportunity to not only provide job opportunities, but also provide much needed skills to equip our youth for the future.

 

We are very proud to announce that we have appointed no less than 11 youth for the 2022 calendar year:

Achieve Better Productivity in your Elemental Analysis: Switch From Flame Atomic Absorption (AAS) to MPAES

Agilent microwave plasma atomic emission spectrometers (MP-AES) have higher sensitivity, lower detection limits (down to sub-ppb levels) and are faster than conventional flame atomic absorption (FAA). MP-AES systems “run on air” instead of combustible gases, so are safer to operate and, in utilizing a nitrogen plasma, are capable of delivering the lowest cost of ownership. When coupled with the extensive range of MP-AES accessories that are also available, you are sure to meet your goals.
