A fundamental component of modern electronic goods is the semiconductor. More powerful, faster and smaller processors are in constant demand for many services and goods because of the advent of the digital age and the current rise of the ‘Internet of Things.’
Grown silicon ingot material has to undergo several processes in order to produce silicon semiconductor devices, including cutting, shaping, polishing and cleaning for further processing. Polishing creates surface planarity necessary for future lithographic steps and so is a key step in order to obtain high quality silicon wafers.
One of the primary technologies for polishing or smoothing the silicon wager surface is Chemical Mechanical Planarization or CMP.

Metrohm’s Approach to Analytical Instrument Qualification (AIQ)
Metrohm’s response to Analytical Instrument Qualification is contained within the Metrohm Compliance Services document, while the most detailed level of documentation offered for AIQ is the IQ/OQ.
Metrohm’s IQ/OQ documentation provides the necessary documentation in close alliance with the main regulations from the USP, FDA, GAMP and PIC/S. This enables good documentation of Metrohm instruments’ suitability for almost any lab’s intended use.

Metrohm’s test procedures can prove that the hardware and software components function appropriately, both individually and as part of an entire system. With Metrohm’s IQ/OQ, users are optimally supported for the integration of its systems into existing current processes.
The Difference Between Raman and SERS

When discussing the feasibility of a low concentration sensing application with a Raman spectroscopist, they are likely to suggest that Raman may not be sensitive enough, but SERS may work.
Yet, that does not get to the core of the actual difference between these two methods, and why SERS (surface-enhanced Raman scattering, or alternatively surface-enhanced Raman spectroscopy) is often recommended for low concentration applications.
Here, the technical differences between Raman and SERS spectroscopies will be explored, as well as some of the practical considerations for how to regard the data for each.
Metrohm USA Announces 9th Annual Young Chemist Award Winner
Metrohm USA is pleased to announce the winner of its 2021 Young Chemist Award, Ryan Jansonius. Ryan is a PhD candidate at the University of British Columbia where his research centers around developing technologies that use inexpensive and abundant renewable electricity to drive otherwise environmentally costly chemical transformations.

The production of fuels, plastics, fertilizers, pharmaceuticals, and specialty chemicals consumes 10% of the energy produced worldwide, and is responsible for 5% of all greenhouse gas emissions. By developing ways to produce these useful chemicals using only abundant feedstocks and renewable electricity, Ryan’s research enables ways to offset these emissions. The aim is to produce renewable diesel, pharmaceuticals and a host of bio-derived specialty chemicals in a way that is cleaner, safer, and cheaper than conventional methods.
