A compact and versatile forensic laboratory instrument, the Laser Induced Breakdown Spectrometer (LIBS) is an ideal tool for elemental analysis of a sample, serving industries such as forensics, archaeology, engineering and ceramics

Laser Induced Breakdown Spectroscopy (LIBS) is a versatile analytical technique which offers significant advantages in speed, sensitivity and cost effectiveness over other processes such as XRF, SEM, and mass spectrometry. LIBS elemental analysis is fast, simple to operate, requires minimal sample preparation, gives immediate results of the elements and is sensitive to low parts per million.

Particle size and size distribution directly influences the material properties, such as rate of dissolution, reaction rate, how it looks and texture.

For example, in paint manufacture may be wanting a certain hue which is defined by the way certain size particles scatter light.

Targeted use will be by paint, coatings, and ceramics industries for quality control testing.

Ability to measure wet and dry samples.

Aimed at the ceramics and engineering industries.

Micro Scratch Tester (MST) is widely used to characterize the practical adhesion failure of thin films and coatings with a typical thickness below 5μm. The Micro Scratch Tester is also used in the analysis of organic and inorganic coatings as well as soft and hard coatings.

Applications include thin and multilayer CVD, PVD, PECVD, photoresist, lacquers, paints, and several other types of films.

Research areas and industries utilize this instrument for microelectronics, optical coatings, protective and decorative surface coatings. Substrates may be soft or hard, including glass, semiconductors, refractive and organic materials.

Impedance is an important parameter used to characterize electronic components, the materials used to make components and electronic circuits.

Impedance analysis can also be used to characterize materials exhibiting dielectric behaviour such as biological tissue, foodstuffs or geological samples. It has a wide range of applications, including material analysis, device characterization, component testing and bio-impedance.

It comes in three distinct hardware implementations, and together these three implementations can probe from ultra low frequency to high frequency and can measure impedances from µΩ to TΩ.

Key specifications of an impedance analyser are the frequency range, impedance range, absolute impedance accuracy and phase angle accuracy.

The contact angle is the angle, conventionally measured through the liquid, where a liquid–vapor interface meets a solid surface. It quantifies the wettability of a solid surface by a liquid via the Young equation.

It changes with surface tension and hence with the temperature and purity of the liquid. The surface roughness has a strong effect on the contact angle and wettability of a surface. The effect of roughness depends on if the droplet will wet the surface grooves or if air pockets will be left between the droplet and the surface.
