Microscopy is often overlooked at Pittcon®, yet of the 12,000+ scientists who attend, approximately 30% use microscopy in some form (according to ongoing research from The Microscopy & Imaging Place, Inc., www.the-mip.com). As clearly demonstrated by the technologies covered in this article, microscopy has become part of the routine analytical scheme. It brings eyes to chemistry, allowing researchers and technologists to see particle size, shape, and distribution; measure spectra on the micro- and nanoscale; and observe processes and properties like never before.
Particle analysis and electron microscopy will both be hot topics at Pittcon 2014, with a number of companies having working systems on the show floor. MicroRaman will also be strong, with interesting new hybrids such as Raman/AFM. And there is something new under the sun in that good old workhorse, light microscopy: Microscopes that are especially comfortable, new camera/communication hubs, and new exhibitors in calibration.
Here’s a quick overview of over two dozen microscopy and related imaging technologies that will be on display on the show floor. Within each technology sector, companies are presented alphabetically. And don’t miss the special educational opportunities listed at the end of the article.
Fluid Imaging Technologies debuts new AutoFocus
Figure 1 – Fluid Imaging Technologies introduces FlowCAM with AutoFocus.
The FlowCAM® imaging particle analyzer from Fluid Imaging Technologies (www.fluidimaging.com) is now available with an AutoFocus feature (Figure 1). This upgrade makes the system even easier to use, and provides a consistent and repeatable fine focus with minimal user interaction.
The AutoFocus Assistant provides on-screen, step-by-step instructions to walk you through the process. Using VisualSpreadsheet® to calculate the ideal focal position, the new AutoFocus assures consistent, repeatable focus every time.
HORIBA announces the new ParticleFinder
HORIBA’s (www.horiba.com/us/en) new ParticleFinder software module (Figure 2) automates particle location and chemical characterization. In combination with HORIBA Raman microscopes (see Spectroscopy, below), ParticleFinder brings a new level of automation and ease of use for particle analysts. It is ideally suited for locating and identifying particulate matter where automated molecular analysis is key, especially for pharmaceutical materials, trace forensic evidence, geological rock/mineral particles, and airborne contaminants trapped on filters.

Malvern features Morphologi G3 and Nanosight particle tracking
The Morphologi G3 automated image analysis system from Malvern (www.malvern.com) is an advanced particle characterization tool for the measurement of particle size and particle shape distributions from 0.5 microns to several millimeters. It offers the flexibility of operation and validation required to support both R&D and automated QC applications. The Morphologi G3-ID adds Raman spectroscopy, delivering component specific size and shape data required to fully understand how formulation and manufacturing methods affect downstream processability and end-product bioavailability.
Also new in the Malvern booth is its recent acquisition: nanoparticle tracking from NanoSight (www.nanosight.com). NanoSight CEO Jeremy Warren reports, “We have always seen Malvern as our natural home. The fit of Nanoparticle Tracking Analysis (NTA) into the Malvern characterization range is crystal clear, plus NTA adds unique nanoparticle counting and concentration measurement. NanoSight will continue as a brand within Malvern, whilst taking advantage of the reach and depth of Malvern’s global channels.”

APPLIED IMAGE brings new calibration to light microscopy
Figure 11 – Today’s more complex measurement needs require more sophisticated NIST and ISO certified standards, such as those from APPLIED IMAGE.
Calibration in the 21st century is no longer a simple subjective determination. In the past, all that was required was a linear scale and a reticle, but this approach is no longer adequate for today’s complex electronic imaging systems. Today’s systems require NIST- or ISO-certified standards for additional calibration of the limiting resolution, contrast capabilities and colors for most instruments. APPLIED IMAGE (www.aig-imaging.com) provides a wide range of standards to meet these needs (Figure 11). In addition, APPLIED can design and manufacture a custom calibration standard to your specific requirements.

TESCAN USA presents Lunch & Learn
Advantages of Variable Pressure in the Electron Microscope
Tuesday, March 4, 12:00 PM
Instructor: Dr. Lisa Chan, Applications Specialist
With some materials, if electrons accumulate on a nonconductive surface, the charge buildup causes a divergence of the electron beam and degrades the SEM image. In the variable-pressure SEM, some air is allowed into the sample chamber, and the interaction between the electron beam and the air molecules creates a cloud of positive ions around the electron beam. These ions will neutralize the negative charge from electrons collecting on the surface of a nonconductive material, whereby an analysis of the sample can be performed. This workshop will show that SEM imaging and EDS chemical analysis can be performed on nonconductive samples, uncoated, when the chamber pressure is maintained at a certain level.
To reserve a seat, contact Colleen Leary at firstname.lastname@example.org.
