Mercaptoacetic acid is often a remarkably poisonous and ablistering compound. Even a 10% solutionwas lethal to most experimental animals by dermal absorption. The oral LD50 price ofundiluted acid is below 50 mg/kg (Patty1963).
This plot, that's generally smoothed, is referred to as a TGA curve. The 1st derivative with the TGA curve (the DTG curve) can be plotted to determine inflection details helpful for in-depth interpretations and also differential thermal Investigation.
Our agent for recognize of promises of copyright infringement on the website is usually reached at: remedies@vwr.com.
Thermogravimetric Examination or thermal gravimetric Assessment (TGA) is usually a method of thermal Investigation where the mass of a sample is calculated over time as the temperature adjustments.
