Advanced HPLC Method Development Using Quality by Design

What does it cover?

The central tenant of Quality by Design (ICH Q8) is that quality cannot be tested into a product – instead it must be designed into the product. When the product is an HPLC method, QbD strategies can guide the development process to result in a standardized method development prcedure, more easily validated methods, and methods that are easier to use and adjust in routine applications.
 “Advanced HPLC Method Development Using Quality by Design” is an intensive online class that teaches you strategy and technique to develop high-quality HPLC and UHPLC methods quickly and with confidence. You will learn a time-proven technique that walks you through the method development process a step at a time using sound chromatographic principles to help make the process more efficient. The techniques can be used as a stand-alone strategy or added to existing development procedures to help streamline the process. Because the same principles apply to HPLC and UHPLC, you can apply the same information for the development of UHPLC methods.

Introduction to Gas Chromatography

What does it cover?

The ‘Introduction to Gas Chromatography’ On-Line Tutorial is basic introduction to the theory and practice of gas chromatographic analysis. It is designed to bring GC users to a more comfortable and capable level of proficiency in instrument operation, optimization, and troubleshooting. Lessons are presented in a visually engaging and accessible manner through narrated on-line video presentations. In full recognition of the difficulty in setting large blocks of uninterrupted time for training; the lessons are presented in short segments that can be easily fit into even the busiest schedules.
• This course presents the basic processes and instrumentation involved with GC analysis.
• The level of material is specifically designed for GC users without extensive formal training.
• Applicable theory is covered to the extent that it helps guide best practices, method optimization and effective troubleshooting.

What will I get from this course?

Upon successful completion of the tutorial, trainees will have increased confidence and skills in using gas chromatographs. They will better understand how GC works, be more competent at detecting and diagnosing problems, and will be better at interpreting the quality of analytical results. In the end, trainees will be more capable and comfortable using gas chromatographs.

Intermediate Gas Chromatography

What does it cover?

The Intermediate Gas Chromatography tutorial is designed for GC users who have a fundamental understanding of how gas chromatography works and who are ready to develop a more in-depth understanding of the technique. As with the ‘Introduction to Gas Chromatography’ course, the ‘Intermediate Gas Chromatography’ course is organized into sections and modules. The sections focus on a given theme and the modular structure underneath exposes students to the information within time-effective sections. The ‘Intermediate Gas Chromatography’ course is a logical next step after completing the ‘Introduction to Gas Chromatography’ course.

What will I get from this is course?

Upon successful completion of the course, trainees will have increased knowledge and skills in development of gas chromatography methods. They will gain an understanding of both qualitative and quantitative methods, as well as expanding their skills to encompass areas such as fast GC, and further developing maintenance and troubleshooting abilities.

LC-MS/MS for Chromatographers

What does it cover?

With the introduction of the mass spectrometer (MS) as a practical detector for a high-performance liquid chromatograph (LC or HPLC) in the early 1990s, LC-MS began to be used for routine applications. One form of LC-MS uses a tandem MS (LC-MS/MS), that has become the go-to instrument for quantitative analysis of drugs in biological matrices in the pharmaceutical laboratory. As they have become more widely used and understood, LC-MS and LC-MS/MS have found their way into environmental applications, synthetic chemistry, protein analysis, and many other areas. LC-MS/MS has moved from a technique available only to skilled experts in both HPLC and MS to a routine tool usable much as any other HPLC detector. You will find that this introductory course in LC-MS/MS will give you a good foundation of understanding the technique and how to use it in your daily work. We start out with an overview of different MS techniques, and focus in the majority of the course on the quadrupole mass spectrometer. You will learn how MS works, how ions are produced and fragmented. Sections focus on qualitative, as well as quantitative analysis. Each part of the process, calibration, tuning, sample preparation, HPLC method development, and MS method development are covered. Many tricks and techniques of practical use are presented.

What will I get from this course? 

You will learn how a mass spectrometer works, the advantages (and limitations) of adding mass spectrometric detection to your liquid chromatographic analyses, and how to use MS to approach separation and detection problems intractable by other methods. By understanding the central roles of the LC-MS interface and the sample ion, you will have a solid grounding on which to further build your LC-MS expertise. You will receive a printed copy of the approximately 515 slides included in this course to supplement your note-taking as you view the class.

Online Monitoring of Atmospheric Inorganic Gases and Aerosols in The Southeastern and Northwestern USA

Atmospheric aerosols exert a large but uncertain negative (cooling) radiative forcing on regional climate. Their chemical composition affects this climate forcing via aerosol hydroscopicity and consequential cloud interactions, as well as providing clues to the chemical origins of the aerosol. A Metrohm Monitor for AeRosol and Gases in Ambient air (MARGA) instrument was used in summer 2013 as part of the Southeastern Oxidant and Aerosol Study (SOAS), a large field campaign that took place in Centerville, Alabama, USA. A MARGA was used to measure the inorganic composition of aerosols and the key gases (HNO3, NH3, SO2) in equilibrium with each aerosol, enabling elucidation of aerosol composition and inferences about origin. The data from this summer field study are compared to data collected in the Pacific Northwest in the fall of 2013, a comparison which helps to isolate the roles of varying regional SO2 sources, humidity, and temperature on aerosol composition and loading.

Latest HPLC Solutions

HPLC Solutions #132: Resources #3: How Do I Validate a Method For...?

This is the third instalment of HPLC Solutions related to resources you should have at your fingertips when you are working in an HPLC laboratory (see also #130, 131). If you work in a regulated industry, such as pharmaceuticals, your HPLC methods likely will need to be validated. If you are using a compendial method from the United States Pharmacopoeia (USP) or European Pharmacopoeia (EP) or other pharmacopoeial method, you may not have to validate the method, but simply demonstrate that it passes system suitability. If the method is modified sufficiently in transfer, it will need some sort of validation.


MS Solutions #28: Quality: The Third Side of the Analytical Success Triangle

As analytical chemists, we spend considerable time thinking about and working with basic scientific principles combined with the technology and products that allow us to solve our analytical problems. However, it is essential for success of any method and for the long-term success of a laboratory operation that our science and technology are supported by a quality system that ensures continuing achievement of our operational goals. We therefore present a triangle concept for analytical success: One side of the triangle shows our need to understand fundamental scientific concepts. A second, and equally sized side, is the ability to apply current technology, applications, software, and techniques in the laboratory. Finally, the base of this equilateral triangle is the quality system. If any one side of the triangle is given inadequate attention or, worse yet, is missing then we cannot hope to achieve overall success for the laboratory operation.
