Model : VT-OA 24 (OA)
Make : V-Tech

Asian handheld oxygen analyzer, which directly displays percentage oxygen on a 31/2 digit liquid crystal display. The mini-oxymeter is equipped with an electrochemical cell as the detector, which is also known as a sensor. PRINCIPLE OF OPERATION The instrument samples gas by diffusion and powered by a 9V battery that has a ‘low batt’ sign indication. The life of the battery is several hours of continuous use. This manual lays out the setting up and operation of the equipment. The oxygen in the sample gas permeates through the semi permeable membrane into the electrolyte, which are immersed in an electrolyte. The cell delivers a current by consuming the lead of its cathode. Expected service life is about 2 years.

PRECAUTIONS IN USE

The oxygen in the sample gas permeates through the semi permeable membrane into the electrolyte, which is in the cell and after reaching the cathode causes at oxidation-reduction reaction. This reaction creates a minute electric current in the external circuit, which is proportional to the partial pressure of oxygen in the sample gas. The signal is then conditioned and compensated for temperatures finally it is converted to a voltage which is fed to the display. The function of the membrane is multifold it not only controls the rate of permeate oxygen in the cathode and protects the analyzing cell from contamination by the sample gas but prevents the immediate evaporation of electrolyte from the cell. Gases heavily laden with water vapor will not affect the cell as long as the vapor does not condense on the cell membrane surface. Remember water vapor also adds its partial pressure to the total pressure and hence if oxygen percentage is to be measured on dry basis this water vapor should be removed from the gaseous mixture. Any simple means can be used e.g. a cartridge of silica gel placed in the sampling line will adequately suit the purpose.

    Turbidity is the cloudiness or haziness of water caused by large numbers of individual particles that are generally invisible to the naked eye. Traditionally samples are taken and the actual turbidity assessment is performed visually by lab personnel or with a multitude of bench-top style turbidity meters. But our ultraportable turbidity meter can measure readings on site and provide a more representative assessment of the actual process conditions. Turbidity is one of the critical parameters observed while evaluating water quality. There are guidelines and standards provided by international institutions for turbidity of water.

     

    Features:

    • Microprocessor based for fast and accurate measurement.
    • Readings can be observed in NTU, FTU & EBC.
    • Large LCD display for reading convenient.

    Introduction

    Nuclear Magnetic Resonance (NMR) was discovered by Bloch and Purcell in the year 1945. Over the years it has developed into a very useful and powerful tool in solid state physics, chemistry and biology. In medical application this technique, under the name Magnetic Resonance Imaging (MRI) has been developed as an excellent imaging method for clinical diagnosis. In this method use is made of Zeeman interaction of the magnetic dipoles associated with the nucleus when placed in a external magnetic field.

    Elementary Magnetic Resonance

    An atom whose nucleus has a nulcear spin I will have a magnetic moment as follows

    = gnI (1)

    where nis nuclear magneton, and g is g-factor. Under the influence of an external static magnetic field (H), these nuclear magnets can orient in distinct directions. Each spin orientation corresponds to a particular energy level given by

    E = gnHmj(2)

    with mj= -I, -(I-1), ...............(I-1), I

    where mjis magnetic quantum number

    The splitting of levels will therefore be-

    DE = gnH or = hn0 (3)

    where n0is the r.f. frequency applied perpendicular to the static magnetic field. Now if the spins are subjected to a purturbation by an oscillating magnetic field with its direction parallel to the static magnetic field and its frequency n1such that the quantum hn1is equal toDE = hn0, we say that there is a resonance between n1and n0. This will induce transition between neighbouring sub levels (mj=I) and in turn will absorb energy from the oscillating field. Thus, at resonance, we get a peak due to the absorption of energy by the system.

    Experimental Technique

    In our experiment the NMR signals of Hydrogen nuclei and Fluorine nuclei are detected. Both have only two possible orientations in reference to static magnetic field H since both have proton spin I = 1/2. The sample is placed in an r.f.coil located between the gap of homogeneous magnetic field H. In order to exactly match equation (3), H is modulated at constant frequency (50Hz in our case) by using two modulation coils. Each time when the matching (resonance) condition (Eq. 3) is fulfilled, energy is absorbed from the r.f.coil due to the spin transition.

    Product DescriptionWith the help of skilled professionals and good knowledgeable experience, we are involved in supplying, exporting and manufacturing quality-assured spectrum of Thermolumniscence Irradiation Unit in Roorkee, Uttarakhand, India.

    Experiment:
    * Microcontroller based menu driven
    * Cost effective solution
    * No radiation hazard
    * High quality double stage rotary pump
    * Long life tesla coil
    * Fully self contained

    Study of Thermoluminescence in alkali halide crystals need creation of F-centres (colour centres) in alkali halide crystals. To produce the F-centres, the crystals are exposed to ionizing radiation which in turn causes the loss of electron from halide ions. An electron then becomes trapped in the halide ion vacancy. The color is the result of the absorption of a photon by the trapped electron and excitation from the ground state to an excited state for the F-center. This is a classic case of particle in a box.

    The source of ionizing radiation could be X-rays, electrons, gamma rays etc. These techniques are too Expensive and unaffordable for normal laboratories. Another method, although little less efficient, is by keeping Alkali halide crystals under low pressure, in the proximity of high Voltage. This in turn produces F-centres in the crystals.

    This later technique has been adopted in this set up to make it economical and affordable for all laboratories. The setup is complete in itself and can be used straight away.
