You Need An H2s Analyzer At Your Lab, Refinery, And Anywhere Else H2s is present. But which One?

H2s Analyzers keep you alive by letting you know when the air is fit to breath

H2s Analyzers come in all shapes, colors, and sizes. https://www.bing.com/images/search?q=h2s+analyzers&FORM=HDRSC2

But, the first question you have to ask yourself is, “What are you going to use the Analyzer for?”

If you are a research firm that is testing samples that you are going onsite to collect a portable unit might suit your needs better than a bulky fixed unit. If you are working in a processing plant or in a pipeline environment, a fixed unit is your best choice for use in the control center to make sure that the H2s in the air is within tolerances. The EPA sets these. However, you should be aware of 1 significant number. 1,000,000 uGm3 is lethal.

Today, we are going to introduce you to some of the various analyzers and the sources of H2s you need to be aware of.

 

Sources of H2s

Most people are concerned with the Air Pollution effects of H2s, which can come from a variety of sources, Paper Mills, Oil Refineries https://cn.bing.com/images/search?q=oil%20refiners%20america, and Natural Gas

Plants. However, you’ll also find H2s in oil tankers https://cn.bing.com/images/search?q=LNG+taker&FORM=HDRSC2, LNG tankers, https://www.bing.com/images/search?q=LNG+taker&FORM=HDRSC2 and inside city sewer tunnels under the street.

 

 

Detection Methods

In a lab, Methylene Blue or Molybdenum Blue are the standards used. Lead Acetate is also used for spot-checking.

Treated paper can also be used that will change color depending on the concentration of H2s in the immediate vicinity. Analyzers often use this in conjunction with a photodiode to give a readout of the amount of H2s present.

Laser Diodes are used with UV light sources to also measure the H2s in the Atmosphere.

 

Some of the companies that manufacture H2s analyzers

Advanced Micro Instruments makes 25 different models of this analyzer. https://www.bing.com/images/search?q=Advanced+Micro+Instruments+H2s+analyzers&FORM=HDRSC2

Another company that makes a line of quality H2s Analyzers is Analytical System Keco. They combine Both H2s and CO2 Analyzers in the same unit. https://liquidgasanalyzers.com/product-category/gas-analyzers/h2s-analyzers/

So, you have a quandary to unravel. How do you get the best of the breed?

 

Stick with the tried and true

Today everyone wants to go high-tech, using UV and Tunable Diode Lasers. However, at the low end, they are not much good. For those who are mostly concerned with the quality of their product. Keeping H2s down to almost zero is desirable.

That’s why the Lead Acetate, a technology from the early 60s, has been revamped to handle the load of today’s petrochemical processing environments.

This redone Technology is much more accurate than the whizz-bang gadgets that the Analyzer Industry is trying to foist on you these days. The tapes used inside the Lead Acetate Analyzers last months now and the units themselves are almost maintenance free and doesn’t require as much calibration as well.

So, when you want to get the accurate readings, try using a tried and true 20th-century technology that has been updated for the 21st century and beyond. https://cn.bing.com/images/search?q=Lead%20Acetate%20H2s%20Analyzers
