SPECTRAL - Specimen preparation for spectroscopy and XR

Optical emission spectrometry (OES) and X-Ray fluorescence 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 Metkon offers manual and automatic sample preparation machines - from the small table-top disc surface grinder to automatic milling machine. With Metkon Sample Preparation Machines, you feel yourself ready for the analysis.

 SPECTRAL 200
Table-top Surface Grinder, for spectroscopic sample preparation of steels and irons, vibration-free construction, robust steel housing, 0.55 kW motor, standard outlet for exhauster, easy to clean and ready for operation.

SPECTRAL 200 is a table-top portable surface grind for the preparation of steel samples for spectroscopy. Its compact design with vibration free operation makes it a practical instrument to work with. Low noise and dust generation levels as well as standard outlet for dust exhauster are additional advantages. 

200 mm grinding disc is dynamically balanced for smooth running. Grinding paper is sucked to the grinding disc which does not require any glue. Papers with 40 – 120 grain can be used to obtain the desired surface quality. SPECTRAL 200 is equipped with electronic brake system bringing the motor to a quick full stop just in seconds after it has been stopped. A safety switch guarantees automatic switch off when the lid is opened.

SPECTRAL 350                              
Dual Disk Surface Grinder,
for spectroscopic sample preparation of steels and irons, course and fine grinding possible on two separate discs of 350 mm dia. which are dynamically balanced, two individual driving motors (2.2 kW each)  with dual speeds of 1400/2800 rpm, equipped with braking device for a rapid stop of the turning discs, suction created by special design retaining the abrasive paper on the disk (no need to  glue or fix), easily replaceable filter, disks covered halfway by lids allowing grinding only on a segment, with interlocking safety switch not allowing the top cover being opened before the motors are stopped, ergonomically designed and ready for operation (wooden packing included).

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

Specimen holder

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 it 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 requirements for any adhesives or fixing attachments. Therefore, the abrasive papers can be used on their full widths and are very easy to exchange.

SPECTRAL PG Pendulum Grinding machine

The 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. Is completely enclosed and dustproof with halogen 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 jut in front of the machine making it ergonomic and easy to handle. It is also possible to prepare other materials by using special stone cup wheels which are easy to exchange.

Vertical movement (Z-axis) for grinding head is motorized with digital positioning and display with 0.01 mm accuracy. Reproducible flat surfaces are achieved with column mounted on taper bearings. Manual V-shaped clamping vice, electro-magnetic and mechanic-magnetic sample holders 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.
