What is the analyzer?

An analyser or analyzer (see spelling differences) is a person or device that analyses given data. An analyser can also be an instrument or device which conducts chemical analysis (or similar analysis) on samples or sample streams. Such samples consist of some type of matter such as solid, liquid, or gas.

Moreover, what is meant by polarizer and analyzer?

If two polarizers are placed one after another (the second polarizer is generally called an analyzer), the mutual angle between their polarizing axes gives the value of θ in Malus’s law.

What is Analyser in optics?

The Rotary Motion Sensor is used to measure the angle between the two polarizing disks. The Light Sensor measures the intensity of light which passes through both polarizers. The Polarization Analyzer — Basic Optics (OS-8533A) is an accessory for the: Basic Optics System (OS-8515C)

What is Malus law of polarization?

Malus’s Law. According to malus, when completely plane polarized light is incident on the analyzer, the intensity I of the light transmitted by the analyzer is directly proportional to the square of the cosine of angle between the transmission axes of the analyzer and the polarizer. i.e I ∞ cos2θ

What is an analyzer technician?

As an Analyzer Technician, you’ll spend your day regulating instruments and equipment. Analyzer Technicians make a great living and are in high demand. They install, calibrate, and maintain some of the most intricate instrumentation in the world. They are highly skilled.

What is a biochemistry analyzer?

The Clinical Biochemistry Analyzer is an instrument that uses the pale yellow supernatant portion (serum) of centrifuged blood sample or a urine sample, and induces reactions using reagents to measure various components, such as sugar, cholesterol, protein, enzyme, etc.

Can a sound wave be polarized?

Sound waves, on the other hand, are longitudinal, meaning that they oscillate parallel to the direction of their motion. Since there is no component of a sound wave’s oscillation that is perpendicular to its motion, sound waves cannot be polarized.

What are process analyzers?

Process analyzers are on-line tools for industrial process analytics. They are used to determine the chemical composition or physical properties of substances involved in industrial processes. Whether for liquid or gas applications, our analyzers can resolve even the most demanding situations.

What is a semi auto analyzer?

Excel™ Excel™ is a semi-automated photometer designed for use in small laboratories that require affordable sample testing. The Excel is controlled by a microprocessor and samples are read using a flowcell module to ensure semi-automatic biochemistry analyzer / compact Microlab 300. Make a request.

What is an automated analyzer?

An automated analyser is a medical laboratory instrument designed to measure different chemicals and other characteristics in a number of biological samples quickly, with minimal human assistance. Play media.

What is the use of electrolyte analyzer?

Electrolyte Analyzer. Electrolyte analyzers measure electrolyte levels in the human body to detect metabolic imbalances and measure renal and cardiac function. The electrolytes measured include sodium (Na+), potassium (K+), chloride (Cl-) and bicarbonate (HCO3- or CO2).

What is a hematology analyzer used for?

Hematology analyzers are used to run tests on blood samples. They are used in the medical field to do white blood cell counts, complete blood counts, reticulocyte analysis, and coagulation tests. Features vary from one hematology analyzer to another, such as closed vial testing and open sampling testing.

What is an ion selective electrode?

An ion-selective electrode (ISE), also known as a specific ion electrode (SIE), is a transducer (or sensor) that converts the activity of a specific ion dissolved in a solution into an electrical potential. The voltage is theoretically dependent on the logarithm of the ionic activity, according to the Nernst equation.

What is the use of reference electrode?

There are many ways reference electrodes are used. The simplest is when the reference electrode is used as a half cell to build an electrochemical cell. This allows the potential of the other half cell to be determined.

What is a membrane electrode?

A membrane electrode assembly (MEA) is an assembled stack of proton exchange membranes (PEM) or alkali anion exchange membrane (AAEM), catalyst and flat plate electrode used in fuel cells and electrolyzers.

What is the gas diffusion layer?

Gas Diffusion Layers. The Gas Diffusion Layer (GDL) is a very important supporting material in a Membrane Electrode Assembly (MEA). The two types of gas diffusion layers most commonly used are carbon paper and carbon cloth.

How does a fuel cell work?

Whether they combine at anode or cathode, together hydrogen and oxygen form water, which drains from the cell. As long as a fuel cell is supplied with hydrogen and oxygen, it will generate electricity. Therefore, fuel cells are more efficient in extracting energy from a fuel.

What are the advantages and disadvantages of fuel cells?

List of Disadvantages of Hydrogen Fuel Cells

  • Nitrogen Dioxide Emission. Critics of hydrogen fuel cells argue that although these cells do not emit carbon after burning, they give out nitrogen dioxide and other emissions.
  • Storage Issues.
  • High Cost.
  • Highly Flammable.
  • Climate Change Aggravation.
  • What are the advantages of using a fuel cell?

    Most fuel cells operate silently, compared to internal combustion engines. They are therefore ideally suited for use within buildings such as hospitals. Fuel cells can eliminate pollution caused by burning fossil fuels; for hydrogen fuelled fuel cells, the only by-product at point of use is water.

    What is the cleanest of all the fossil fuels?

    When burned, natural gas releases up to 50% less CO2 than coal and 20-30% less than oil; When used in power generation, natural gas emits as much as 50% less CO2 than coal, results in negligible emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), mercury (Hg), and particulates compared with other fuels.

    How much does it cost to make a hydrogen fuel cell?

    Until recently, the platinum catalyst that splits the hydrogen into an ion and an electron has been prohibitively expensive. Up to a few years ago, hydrogen fuel cells cost around $1000 for every kilowatt of power they generated – or around $100,000 per car.

    Is hydrogen fuel cheaper than gasoline?

    It is very clear that Hydrogen is cheaper than Gasoline or Diesel. At the current price,Gasoline costs 275% more than Hydrogen gas. By reducing the cost of solar panels to less than $1.00 per watt, Renewable Hydrogen will become a commercial reality and that will be the end of fossil fuels.

    How much does a gallon of hydrogen fuel cost?

    Long Answer: Hydrogen fuel prices range from $12.85 to more than $16 per kilogram (kg), but the most common price is $13.99 per kg (equivalent on a price per energy basis to $5.60 per gallon of gasoline), which translates to an operating cost of $0.21 per mile.

    What is polarizer and analyzer?

    A polarizer or polariser is an optical filter that lets light waves of a specific polarization pass through while blocking light waves of other polarizations. It can convert a beam of light of undefined or mixed polarization into a beam of well-defined polarization, that is polarized light.
