The Single-Bullet Theory Comes to New York – But Was it a Direct Hit?
November 22nd 2023Pete Diaczuk of John Jay College of Criminal Justice gave a recollection at EAS 2023 of a case he worked on in Manhattan involving a victim fatally shot, incomplete ballistic evidence, and the wrong gun recovered at the scene.
Standardizing Solutions to Enabling Platforming of Process Analytical Technology (PAT) Deployments
April 24th 2023Gary McGeorge, Scientific Director at Bristol-Myers Squibb, spoke to us of the benefits and challenges associated with establishment of consistent resolutions while facilitating the steps associated with the implementation of process analytical technology (PAT).
Pump–Probe Microscopy: Theory, Instrumentation, and Applications
April 1st 2017Excited state dynamics provides an intrinsic molecular contrast of samples examined. These dynamics can be monitored by pump probe spectroscopy which measures the change in transmission of a probe beam induced by a pump beam. With superior detection sensitivity, chemical specificity and spatial-temporal resolution, pump probe microscopy is an emerging tool for functional imaging of non-fluorescent chromophores and nanomaterials. This article reviews the basic principle, instrumentation strategy, data analysis methods, and applications of pump probe microscopy. A brief outlook is provided.
Review of New Spectroscopic Instrumentation 2016
May 1st 2016Our annual review of products introduced at Pittcon or during the previous year, broken down by the following categories: accessories, atomic spectroscopy, components, imaging, mass spectrometry, mid-IR, NIR, NMR, Raman, software, UV-vis, and X-ray.
Trends in Spectroscopic Instrumentation: Complex Measurement Needs Drive Instrument Design
March 1st 2016This article discusses emerging trends in the design and use of spectroscopic instrumentation. It focuses on recent research using new or modified spectroscopic techniques that are advancing scientists’ capability to obtain high-content, high-resolution data from ever-smaller sample sizes. To illustrate this trend, the article surveys novel approaches to complex measurement problems across a wide range of critical fields such as disease research, food safety, environmental monitoring, and drug development.
2015 Review of Spectroscopic Instrumentation
May 1st 2015Every year, we prepare this review of new spectroscopy products to make it easy for you to stay up to date on the latest instrumentation, accessories, components, and software. Traditionally, we have referred to this article as the "Pittcon" review.
