Measures dynamic viscosity and density of oils and fuels according to ASTM D7042.

Proper selection and use of viscosity instrumentation can bring valuable time savings to test programs in todays busy labs. Increased data throughput, coupled with detailed analysis, is a new horizon that has potential to offer enhanced quality control.

Useful viscometer / rheometer features that buyers should be aware of are temperature control, spindle rotational speed control, a range of sample holders, and ease of use.

Since size dictates so many properties of materials, particle size measurement is critical for many industries.

Gas chromatography-mass spectrometry (GC-MS) is the fastest-growing GC method.

With the cost of an upper echelon field emission scanning electron microscope approaching $1 million, a pre-owned SEM becomes a cost-effective possibility. But before purchasing any SEM, new or used, a couple of questions need to be answered.

Delivers a resolving power of greater than 60,000 (FWHM) over a wide mass range of m/z 10-30,000.

Provides tunable resolution of 4,000 to 7,000 at FWHM at m/z 281.

Invented in the late 16th century, the microscope is arguably the oldest laboratory instrument. Yet despite its maturity, microscopy continues to evolve toward greater capabilities.

Dr. Rebecca Williams, director of the Microscopy and Imaging Facility at Cornell University, talks about her role in overseeing the imaging laboratory while pursuing independent research in the field.

Increasingly, analysts perform routine analysis where the action islocations of environmental interest, manufacturing suites, crime scenes, loading docks, and packaging facilities through transportable instruments.
