Introduction

Angstrom Advanced Inc HGH-300 and HGH-500 high purity portable hydrogen generators are based on the technology of astronautic fuel cells, in which hydrogen is produced by the electrolysis of water, and the produced oxygen is released into the atmosphere. The generator consists of electrolyzing/separating pool, power supply, pressure control, desiccation& purification, flow display etc. The core part -- electrolyzing & separating pool, uses a tube shaped positive pole and a plate shaped negative pole. Both poles are made of stainless steel. The electrolyzing & separating pools store electrolytes, produce hydrogen as well as release hydrogen at the same time.
The Angstrom Advanced HGH series hydrogen generators have the advantages of large electrolyzing area, low temperature of the pool, better performance, high production and high purity of hydrogen. The instrument has been specially designed to prevent liquid from back-flowing.

Features

·         It is very easy to operate -- all you need is to turn on the switch.
·         The pressure of released hydrogen is steady. The flow rate is digitally displayed on the LED display.
·         The only material that the instruments consume is distilled water.
·         The liquid storage, hydrogen electrolyzing and desorbing are integrated together in the instrument
·         The generator features large electrolyzing area, low pool temperature, long service life combined with high production and high purity of hydrogen.
·         The instrument has specially designed components that prevent liquid from back-flowing. As a result, there is no need to change the discolored silica gel frequently.
·         The adoption of the advanced power switches improves the electrolytic efficiency.
·         The generator is a great substitute of high-pressure steel bottles used in the laboratory application.

Angstrom Advanced AFM / SPM Modes and Scanner Technology


SPM Tapping Mode:

In Tapping Mode, a cantilever is oscillating in free air at its resonant frequency. A piezo stack excites the cantilever’s substrate vertically, causing the tip to bounce up and down. As the cantilever bounces vertically, the reflected laser beam is deflected in a regular pattern over a photodiode array, generating a sinusoidal electronic signal. And this signal is converted to a root mean square (RMS) amplitude value. 

When the same cantilever is oscillating at the sample surface, Although the piezo stack continues to excite the cantilever’s substrate with the same energy, the tip is deflected in its encounter with the surface. The reflected laser beam reveals information about the vertical height of the sample surface.


The feedback system controls the scanner’s Z voltage to maintain the tip-sample force constant, which leads the Up-Down signal equals to the Setpoint. The Z voltage is recorded for calculating the sample topography.


  • Figure 1: No force between tip and sample, no cantilever deflection.
  • Figure 2: Repulsion between tip and sample, cantilever deflects upside.
  • Figure 3: Repulsion between tip and sample, cantilever deflects upside:
    • X: Deflection of cantilever
    • k: Force constant of cantilever
    • F=kx


The sample is placed on the Piezo Electric Scanner and is scanned under a stationary cantalever tip (there are AFM models in which the tip is scanned over a stationary sample). The PES is a very precise component and is able to accuratly move the sample through a scan (a back and forth raster pattern) of only a few hundred nanometers. Scanners are made of piezo tubes and are steady held in the SPM base.Voltage applied to piezoelectric scanner tube housed inside moves sample precise increments back and forth. Size at bottom indicates maximum size scan possible,each scanner has its own specified parameters.

Samples are held in place on the scanner with a removable cap.Piezo scanner can extend and retract 3-dimentionally based on the applied X, Y and Z voltage placed across the individual elements.
