Data Store FunctionThe Ram has the capability of saving 200 separate groups of data which can be recalled at any time and most importantly, if a sudden loss of power occurs. Users don't need to write down each test result in the notebook, thus saving time and increasing work efficiency. Standard Curve Build and Store Users can build their own standard curve on the screen and save it within the RAM. The curves can be reloaded at any time. Up to 100 curves can be stored. Coefficient Method If you know the coefficients of the curve equation, you can input the values and use them to test the samples directly. Kinetics Test The Kinetics curve can be displayed in the screen, you can use this function to test the samples and verify the instruments stability. System Function The instruments have the ability to calibrate the wavelength accuracy and dark current automatically by choosing the corresponding command in the Utility menu. Super PC Software (Optional) The software functions include 1) Kinetics 2) Quantitative Test 3) Wavelength Scan 4) Multi wavelength Test 5) DNA/Protein Test

Features

The Milas Deuterium is a world-leading lamp that has a long-lasting service life, high stability and high brightness. The Tungsten lamp also ensures a long service life and high stability on the UV spectrophotometer. The lamps feature pre-aligned design, so there is no need for professional adjustment while replacing a new one. Therefore users no longer need to hire professionals to change or adjust lamps which greatly improves reliability and cuts down on the maintenance expenses. The D2 lamp and the W lamp can be controlled individually to extend the lifetime. You can switch off the D2 lamp when in visible range or switch off the W lamp when in Ultraviolet range. Excellent optical performance Low Stray Light The Stray Light is only 0.05%T which enables the user to decrease the analysis Relative Error greatly. High Wavelength Accuracy Adopt advanced Guide Screw structure, which ensures the wavelength accuracy and repeatability. Outstanding UV and visible region are used with corresponding photometry accuracy of top-grade instruments (NBS930D standard, standard solution), which enables the instrument to be suitable for various quality control.

Angstrom Advanced Hydrogen Generating Plant by Pressure Swing Adsorption with Purifying System

Introduction

Pressure Swing Adsorption(PSA) is used to separate hydrogen gas from other gases by feeding the gas under certain pressure. This separation process occurs in adsorption tower. The main advantages behind this technology is its low cost, low capacity, minimal maintenance requirements and a user-friendly interface. The H2 Purifying System removes oxygen from Hydrogen via a catalyst to get high purity H2 after adsorption of drying through the dust filter. The system can remove oxygen levels down to 1ppm. Through one step of purification, the purity can reach to 99.999~99.9999% and dew point can be lower than -70°C; Through a second purification step, O2 can be lowered down to less than 0.1ppm and dew point can be lowered to -90°C. Specifications

H2 capacity	10-5000 Nm3/h
Dew Point	≤-60C
H2 purity %	>98-99.999%
Work pressure	0.2-4.0MPa

PSA Process Overview

Pressure-Swing Adsorption or PSA is a technical process widely used these days in gas production. It's a typically non-cryogenic way of purifying gas. PSA process differs from cryogenic techniques of gas separation as it can function under near-ambient temperatures. Under pressure, the PSA process separates some 'species' from a mixture, according to the molecular characteristics of those 'species'. This is because different gases has the propensity to be attracted to different solid surfaces more or less strongly. More gas is adsorbed at higher pressure while the gas is desorbed as the pressure is reduced. Suppose air under pressure is passed through a vessel containing an adsorbent bed and this bed has the property to attract nitrogen more strongly than oxygen. What will happen is that a part or all of the nitrogen will remain in the bed, while the gas coming out of the vessel will be enriched in oxygen. As the bed reaches its optimum capacity to adsorb nitrogen, it can again be regenerated by reducing the pressure. Releasing the adsorbed nitrogen in the process. Thus readying itself for another cycle of oxygen enriched air. This cycle goes on. Popular adsorptive materials like carbon, zeolites, silica etc. are used as the adsorbent beds. They selectively adsorbs the undesired gases at high pressure on their surface. Continuous production of the target gas is achieved by using more than one adsorbent chamber. However it is not a very easy process and difficult to model accurately. But once properly modeled, adsorption process can result in complex diffusion relationships.

Angstrom Advanced Hydrogen Generating Plant by Ammonia Decomposition

Hydrogen Generator by Ammonia Decomposition with Purifying System is very low cost; it has long service life, simple operation, compact structure, small coverage, and is very simple to install. Liquid ammonia is used as source for hydrogen generator. The liquid ammonia is vaporized and is heated by decomposition with catalyst into mixed gas containing 75% hydrogen and 25% nitrogen.

Electrolysis Process Overview

Electrolysis is the passage of a direct electric current through an ionic substance that is either molten or dissolved in a suitable solvent, resulting in chemical reactions at the electrodes and separation of materials. The main components required to achieve electrolysis are : An electrolyte : a substance containing free ions which are the carriers of electric current in the electrolyte. If the ions are not mobile, as in a solid salt then electrolysis cannot occur. A direct current (DC) supply : provides the energy necessary to create or discharge the ions in the electrolyte. Electric current is carried by electrons in the external circuit. Two electrodes : an electrical conductor which provides the physical interface between the electrical circuit providing the energy and the electrolyte. Electrodes of metal, graphite and semiconductor material are widely used. Choice of suitable electrode depends on chemical reactivity between the electrode and electrolyte and the cost of manufacture.
