The region lying between TD-THz and the mid-IR, the far-infrared (far-IR: ∼ 30−400 cm −1), is not nearly as well utilised for routine chemical analysis, let alone screening

Diethyl ether resulted in a greater yield of methamphetamine salts than camp fuel. Abstract . Following the first discovery in 2007, One Pot methamphetamine laboratories have

Rapid Nondestructive On-Site Screening of Methylamphetamine Seizures by Attenuated Total Reflection Fourier Transform Infrared Spectroscopy

The matrix-matched calibrations were prepared for each type of matrix with regression coefficients 0.9943-1.0000. The calibration curves were linear in the concentration

The infrared transmission spectra of some hydrogen halide salts of methamphetamine are observed to display significant variations dependent upon the alkali halide matrix in which the

This approach exploits the solid-state, ion-exchange reaction between methamphetamine hydrochloride and a potassium iodide matrix and the subsequent formation of the hydriodide

6.4B: Accounting for Matrix Effects

The region lying between TD-THz and the mid-IR, the far-infrared (far-IR: ∼ 30−400 cm −1), is not nearly as well utilised for routine chemical analysis, let alone screening

Ninety six illicit drug seizures containing methamphetamine (0.1%-78.6%) were analysed using Fourier Transform Infrared Spectroscopy with an Attenuated Total Reflectance

Both amphetamine and methamphetamine possess a stereocenter. The stimulating effect of the (S)-enantiomers are 3–4 times higher than the (R)-enantiomers [3].(S)

In this study, the physical and chemical profiles of seized illicit methamphetamine tablets were obtained employing various analytical techniques, including physical examination, attenuated

This is consistent with previous studies that reported the positive effects of cognitive methods on depression and posttraumatic stress disorder signs and symptoms in non– amphetamine

Examination of thermal decomposition of street samples of cocaine and methamphetamine shows that typical products detected in previous studies are accompanied by a wide palette of simple

When describing the matrix effects in illicit drug analysis mass spectrometry is often used as the guiding instrument because, even though it offers the analyst great sensitivity

Analytical parameters evaluated and resulting data are as follows: (i) average extraction recoveries (n = 3) were better than 80%, except for MDMA (71%) and morphine (74%); (ii) inter

Methods to quickly purify methamphetamine hydrochloride from the cutting agent dimethyl sulfone for subsequent identification of confiscated crystalline samples using infrared

Ninety six illicit drug seizures containing methamphetamine (0.1%–78.6%) were analysed using Fourier Transform Infrared Spectroscopy with an Attenuated Total Reflectance attachment and Chemometrics. Two Partial Least Squares

These effects appear to arise from a chemical exchange of halide ions between the methamphetamine salt and the matrix material, which can complicate the interpretation of the

Synchrotron far-infrared (far-IR) spectra were measured for a representative set of pharmaceutical-type molecular crystals: phenylethylamine hydrochloride salt, ephedrine base

The infrared transmission spectra of some hydrogen halide salts of methamphetamine are observed to display significant variations dependent upon the alkali

In this study, we examined phenethylamine, 3,4-methylenedioxyphenethylamine, tryptamine, N-methylephedrine, and nicotine as well as analogues of amine-related psychoactive substances

Ninety six illicit drug seizures containing methamphetamine (0.1%–78.6%) were analysed using Fourier Transform Infrared Spectroscopy with an Attenuated Total Reflectance attachment and

Vapour-phase infrared analysis The samples were prepared as described in Section 2.4.1, with an injection volume of 4 mL. The vapour phase infrared spectra were collected using an Agilent

In this study, a modified LC-ESI-MS/MS method for the simultaneous determination of MA and its isomer N-isopropylbenzylamine (N-IBA) in forensic samples was developed and

Solid phase infrared (IR) spectra (Fig. 1) were obtained using an ATI-Mattson Genesis Series Fourier Transform Infrared Spectrophotometer interfaced with a Dell
