MATERIALS TESTING | EQUIPMENT
Integration of multiple analytical techniques is designed to allow users to conduct correlative analysis.
Additional features of the Thermo Scientific
Nexsa surface analysis system include: a small spot x-ray source designed to improve the imaging capabilities compared to previous instruments; the ability to transfer air-sensitive materials into the instrument without exposure to the atmosphere either via an optional vacuum transfer module or integration with an external glove box; and optional integration with the Thermo Scientific MAGCIS dual mode ion source to enable depth profiling of soft materials, such as polymers. Thermo Scientific has also developed the iXR
Raman spectrometer, a new multi-modal Raman spectrometer in a compact design that provides simultaneous analysis of a single measurement point using multiple analytical techniques, allowing relationships between molecular composition, surface performance and structural performance to be established. The equipment uses optical interfacing to provide a chemical fingerprint and material structure data simultaneously while gathering elemental or physical information from complementary instrumentation. In addition, with the Thermo Scientific OMNIC Series Software, the iXR Raman spectrometer can capture spectroscop- ic changes over time, enabling measurement of dynamic processes or changing conditions, such as the crystallisation of a polymer in a rheological study.
Simple FTIR Also new from the company is the T Nicolet iN5 FTIR microscope, which is designed as a simple, cost-effective solution for particulate identification in the laboratory. The company says the robust iN5 FTIR microscope features an optical setup that allows users to examine a sample and collect chemical information simultaneously. A large field of view is intended to make it easier to locate and target contaminants, and it has the spatial resolu- tion required for accurate chemical analysis. The microscope uses the Thermo Scientific Omnic software which, with its extensive set of libraries, can match samples in real time to enable more confident decisions with minimal user training. It is designed for use with the Thermo Scientific line of infrared spectrometers. Shimadzu has launched the MALDI-8020 matrix assisted laser desorption ionisation-time of flight (MALDI-TOF) mass spectrometer. The company says it offers the highest level of resolution and sensitivity of a linear benchtop model designed

for installation on a laboratory workbench. In comparison to quadrupole and magnetic field systems, MALDI-TOF mass spectrometers offer the advantage of both a wide measurable mass range and high mass resolution. This latest model is also much smaller, measuring just 1m high compared to the more typical 2m height of previous equipment, which provides more flexibility in installation locations. The new instrument is suitable for determining the molecular weight of polymers. The laser repetition rate has been increased from 50 Hz for existing models to 200 Hz through the introduction of a solid-state laser and sample introduction time has been shortened. In addition, measurement time has been significantly reduced by increasing the speed of the stage and the need for mainte- nance and inspections has been reduced, lowering running costs.
Performance SPM Shimadzu has also recently introduced the SPM- 8100FM scanning probe microscope (SPM), featuring five times faster data acquisition, four times wider scan in both X and Y-axis directions, and ultra-high resolution performance that is as high in air and liquids as in a vacuum. SPMs scan the surface of a sample using a cantilever fitted with a fine probe – with a tip radius of just a few nanometres – to measure the surface topology and physical properties of a sample. The SPM-8100FM is an atomic force microscope (AFM) type which can be used to analyse polymers and local struc- ture at solid-liquid interfaces.
