Sensors availability to detect the styrene, acrylonitrile and butadiene

Hello Everyone,
I want the detect the acrylonitrile, butadiene and styrene with the help of sensors. Is it possible? or I have to go through GC-MS or TGA?

Greetings,

One would need to define the question more precisely to arrive at an answer. There is a significant difference between differentiating a specific substance from other similar substances, detecting presence of a class of substances in an environment where they are normally uncommon, detecting things at tiny versus high concentrations, etc.

It is also unclear whether you refer to these substances separately or in their combined form as the common ABS polymer.

Hi Rick,
First of all thank you for your reply and interest in my question and sorry for my late reply and short question.
Acrylonitrile, butadiene and styrene as we know that these elements are classified as carcinogens in different classes by IARC and other agencies.

  1. I would like to find out the above three elements which are present in emission with other elements like formaldehyde, COx gases and other VOC.
  2. Amount of these elements versus other elements
  3. If ABS is blended with PC and other additives what will be the % of these elements in emission?
  4. My aim is to detect the emission elements with the help of law cost sensors, without separating them from emission, in short avoiding the sampling techniques and further process like GC-MS or TGMA if possible. Obviously for validation GC-MS and TGMA can be preferable but later on sensor based detection system will work or not? I hope I have narrated. Eager to learn and listen to you.

First, Iā€™d like to mention that the gas sensors we have available for sale can be found here.

In general, low-cost gas sensors are most useful for detection and monitoring applications where it is known that a specific compound may be present, such as alarms for carbon dioxide or explosive gasses. They are not very effective for analysis applications where a person wants to determine what different gasses are present and in what concentrations.

Looking at the table of sensitivities for the PS4-VOC-1000 for example, its sensitivity to some of the different gasses mentioned can vary by nearly 200x.
