| Our systems for gas permeability measurement for plastic and rubber samples have simplicity, excellent selectivity, high sensitivity and wide dynamic range. The measurable permeating components include water vapor, hydrogen-sulfide, methane, ethane, carbon-dioxide, BTEX (Benzene, Toluene, Ethyl Benzene and Xylene), ammonia etc. There are two basic forms of our systems; the first one, which is based on photoacoustic gas detection, is optimal for measurements at normal pressure and temperatures up to 120 ° C. The second one, which is based on photothermal beam deflection method, can be used also at extreme pressures (up to 1000 bar) and also at high temperatures. An outstanding feature of our system is that due to the very high dynamic range of the measuring method, it is possible to fit numerically the early part of the permeation curve, which results in a considerable reduction of the measurement time |

The oxidation stability of biodiesel can easily be determined with the 873 Biodiesel Rancimat from Metrohm, a modern and reliable instrument with a 3 years’ warranty. In addition to reliable hardware and easy operation, it offers all the comfort to be expected from a PC-controlled instrument.
The method: oxidation stability according to EN 14112
The determination of the oxidation stability according to EN 14112 is an accelerated oxidation test. The sample is held in a sealed reaction tube at a constant temperature of 110 °C while a continuous flow of air is passed through the sample. The fatty acid methyl esters (FAME) in the sample are oxidized to peroxides as the primarily oxidation products. After some time, the fatty acids are completely decomposed into the secondary oxidation products. In addition to volatile organic compounds, these are low-molecular organic acids, mainly formic and acetic acids. An air flow transports them to a measuring vessel containing distilled water as the absorption solution. |

Ear Measuring Instrument, Model 126
Used to obtain a numerical value of the size of the ears resulting from anisotropy in the material of cylindrical deep-drawn cups (e. g. according to DIN 50 155). The average cup height, the height of the ears in percent and in mm can be read-off at a touch of a button and are shown on the digital display instrument. To enable additional data processing the test instrument can be equipped with interfaces, such as BCD or RS 232 C outputs and with a printer. |

| PolaWiseTM is an advanced polarization measurement system for accurate characterization of all polarization related properties of light sources and optical materials. Based on General Photonics' patented magneto-optic polarization generation and analysis technology, the PSGA-101-A is specially designed for fiber optic applications and can effortlessly accomplish multiple functions, including polarization state generation (PSG), polarization state analysis (PSA), polarization extinction ratio (PER) measurement, polarization dependent loss (PDL) measurement, and polarization mode dispersion (PMD) measurement. Another attractive feature of the instrument is its large flip-top LCD graphic display design, an industry first that allows large viewing area on a compact, portable enclosure. Furthermore, a 2x20 character LCD is also included on the front panel for easy operation of the instrument for applications that do not require a graphic display, such as PER measurement. The instrument comes with an internal tunable laser for PDL and PMD measurement up to 10 ps. It can also control tunable lasers from third parties via a GPIB port for measurement of larger PMD values. The instrument also comes with a VGA port for use with an external LCD graphic display of the user's choice. PolaWiseTM: a wise instrument and a smart choice! |

one hand and 3D topography or film thickness on the other.
All tools are metrological and comply with the necessary industry
standards such as the SECS II / GEM software interface.
Furthermore, the system is fully automated and equipped
with wafer cassettes and part carriers.
An EFEM and mini-environment for class 1 cleanrooms
rounds off the upper segment of the MFE tool series. |
