Sample Preparation for Spectroscopy - SPECTRAL Series

Qualitest covers a complete range of instruments for Optical emission spectrometry (OES) and X-Ray fluorescence which are most commonly used techniques for the analysis of metals and solid samples.

Sample preparation of metals and materials have become more and more important because of the rapid development and improvement of both software as well as OES and XRF-devices during the past few years that shifts the detection limit for trace analyses. It is crucial to have the sample properly prepared.

The sample needs to be both representative, homogeneous and with an even surface in order to eliminate factors that can influence the results.

For the preparation of solid metal samples Qualitest offers manual and automatic sample preparation machines - from the small table-top disc surface grinder to automatic milling machine. With our Sample Preparation Machines, you feel yourself ready for the analysis.

Sample Preparation for Spectroscopy - SPECTRAL 350

SPECTRAL 350 Dual Disc Grinder is used to achieve excellent precision flat surfaces of iron and steel samples for spectroscopic analysis. The robust and vibration-free construction has been designed for continuous operation at high sample throughput.

SPECTRAL 350 has two independently driven grinding discs of 350 mm which are dynamically balanced for smooth running and the speed of each disc can be set either to 1400 RPM or 2800 RPM. Coarse and fine grinding on two separate grinding discs can be done on the same machine. Due to its special design, grinding paper is sucked to the grinding disc which does not require any glue. SPECTRAL 350 can be equipped with a strong aspiration device in addition to its special design, increasing vacuum for suction which retains the abrasive paper on the disc, eliminating the requirement for any adhesives or fixing attachments. Therefore, the abrasive papers can be used on their full widths and are very easy to exchange. Strong Aspiration Device (Blower) unit available as an accessory with easily replaceable filter creates a dust-free working environment. Both discs are covered halfway by a lid and the sheet metal only allows grinding per segment for the operator’s comfort and protection. Magnetic and mechanical specimen holders are available to ensure maximum operator safety. SPECTRAL 350 is further equipped with breaking device permitting a rapid stopping of the turning discs. The machine is fitted with an interlocking safety device the permits the lid from being opened before the motors are stopped.

Sample Preparation for Spectroscopy - SPECTRAL PG

SPECTRAL PG is a compact bench-top pendulum grinder for fast grinding of iron and steel samples for spectroscopic analysis. It has a simple and reliable design with low noise and dust generation levels. It is completely enclosed and dust-proof with LED spot light. The front cover can be completely opened for easy access to all sides.

SPECTRAL PG is suitable for wet and dry grinding with minimum maintenance required which is mainly cleaning. It is possible to attach an external dust exhauster to the standard outlet at the rear side. The grinding arm is placed just in front of the machine making it ergonomic and easy to handle. SPECTRAL PG is especially suitable to grind hard materials like white cast irons. It is also possible to prepare other materials by using special stone cup wheels which are easy to exchange. Vertical movement (Z axis) of grinding head is by hand wheel in front and positioning with 0,01 mm accuracy is possible. Reproducible flat surfaces are achieved with column mounted on taper bearings. Manual V shaped clamping vice, Electromagnetic and Mechano-magnetic plates are available as accessories. Spectral PG is equipped with braking device permitting a rapid stop of the grinding wheel. The machine is fitted with an interlocking safety device not allowing the hood being opened before the grinding motor is stopped

Sample Preparation for Spectroscopy - SPECTRAL MM

An automatic milling machine for fast milling of non-ferrous and steel samples for emission and X-ray spectrometer analysis. Automatic fine surface milling guarantees the highest level of reproducibility through automatic processing of the specimen. SPECTRAL MM has a robust and reliable design with low noise and emission levels. It is completely enclosed and sound-insulated with LED spot-light. The front cover can be completely opened for easy access to all sides. The unit is equipped with automatic sample feed with fine speed control. Fast advance and reverse are available. All important parameters of the milling process like feed rate, milling depth, spindle speed are adjustable on the touch screen LCD. The spindle speed can be adjusted to different materials to achieve optimum surfaces. Reproducible flat surfaces are obtained with column mounted on taper bearings. SPECTRAL MM is suitable for different sample shapes (cylindrical, mushroom shaped etc.) with diameters up to 80 mm. It can be fitted with special cutter head with 8” diamond or tungsten carbide tips. Three-point-chuck is included in the standard scope of supply of the machine. Other additional clamping devices are available as optional accessories.

SPECTRAL MM is equipped with highest level of the safety standards. Several safety circuits guarantee optimum protection for the operator. An electronic brake system is integrated to the system for a rapid stop of the milling head. The interlocking safety device does not allow the hood to be opened before the milling motor is stopped.
