Measuring range 0-100% capacity in % 0-8 absorption m-1
Measurement chambereffective length 0.430 m ± 0.005 m
Heating Time220 V …….approx. 20 min
Light sourceHalogen bulb 12 V/ 5W
Colour temperature3000 K ± 150 K
Detector Selenium photocell dia. 45 mm Max. sensitivity in light,
In Frequency range 550 to 570nm.Below 430 nm and above 680 nm sensitivity is less than 4% related to the maximum sensitivity
Maximum Smoke2100 C Temperature at entrance.
Principle: The operating principle is based on the attenuation of a light beam caused by the exhaust gases in a measuring chamber of defined measuring length, and nonreflecting surface filled homogeneously with the exhaust gas. The loss of light intensity between the light source and a receiver is measured and reported in % opacity, the calculation being based on the Beer Lambert law. The absorption coefficient “k” was also reported by the smoke meter, in accordance with the ECE-R24/ISO 3173. Condensation inside the instrument is avoided, as the measuring chamber is thermostatically heat controlled at 70 ± 5 oC.
Application: The smoke meter is used to measure the smoke emission from stationary diesel engines.

Principle: The GC-MS is composed of two major building blocks: the gas chromatograph and the mass spectrometer. The gas chromatograph utilizes a capillary column which depends on the columns dimensions (length, diameter, film thickness) as well as the phase properties (e.g. 5% phenyl polysiloxane). The difference in the chemical properties between different molecules in a mixture and their relative affinity for the stationary phase of the column will promote separation of the molecules as the sample travels the length of the column. The molecules are retained by the column and then elute (come off) from the column at different times (called the retention time), and this allows the mass spectrometer downstream to capture, ionize, accelerate, deflect, and detect the ionized molecules separately. The mass spectrometer does this by breaking each molecule into ionized fragments and detecting these fragments using their mass-to-charge ratio.
Application: The GCMS system is targeted for organic, biological, pharmaceutical & polymeric sample analysis (Detection and identification). Only liquid sample with less than 1000Da.
