What is a HazCat kit?
HazCat Chemical Identification Systems Used by the EPA for field and in-lab identification. We are the sole manufacturer of the DHS approved HazCat® kits, the most accurate field identification system in the world.
What is chemical identification?
Chemical identification is considered to be assigning an analyte (analytical signal) to one of the set of known individual chemical compounds or to a group/class of compounds based on matching their properties [5], [12]. Procedures of detection and identification are united within qualitative chemical analysis.
What does the first defender detect?
FirstDefender RMX portable chemistry analyzer Identifies explosives, toxic industrial chemicals (TICs), chemical warfare agents (CWAs), narcotics, precursors, white powders and more.
How does the first defender work?
A FirstDefender is a little like that. It uses Raman spectroscopy to quickly identify molecules by shining a laser light on them. Inside the laboratory, these techniques have been commonly used for three or four decades, but in the past 10 years, Raman devices have become progressively more portable and, now, handheld.
How do you find chemical identity?
The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes.
Why is it important to identify unknown substances?
Detecting known substances, and determining their quantity, is also important. In manufacturing, it is important to detect any impurities in the product and to determine whether they are present in a significant amount. Analytical characterization is critical in pharmaceutical products, for instance.
What is substance Z?
Substance Z is water which is neutral compound.
What tests can be done to identify an unknown substance?
Where might you come into contact with unknown chemicals in the real world?
How can you identify an unknown material?
Some methods and technologies we use include:
- Gas Chromatography (GC)
- Gas Chromatography Mass Spectroscopy (GC-MS)
- Ion Chromatography (IC)
- High Performance Liquid Chromatography (HPLC)
- Dispersive Raman Spectroscopy.
- Fourier Transfer Infrared Spectroscopy (FTIR)
How do you know that they are liquid and not something else?
The simplest way to determine if something is a liquid is to ask this question: If I try and move it from one container to another (i.e. by pouring), will it conform to (take on the shape of) the new container? We can pour liquid water from one container into another. Liquid water takes on the shape of its container.
What would be most useful for identifying an unknown liquid?
When observing different liquids, the way a liquid acts on paper is a characteristic property of the liquid and can be used to identify it. For the test to be fair, the same amount of each liquid should be placed on the paper in the same way.
