Introduction
LC-MS/MS has become a preferred method for the routine analysis for forensic toxicology. LC-MS/MS allows for the simultaneous analysis of multiple compounds in a single run, thus enabling a fast and high throughput analysis. In recent years that it seems the number of incident and accident is increasing caused by dosed with psychotropic drugs and the number of drug testing with LC-MS/MS is also increasing to investigate the cause of death. However, manual sample preparation often involves several complicated manual steps which can introduce error into the results. In this study, we investigated the processing capability to analyze serum, whole blood and urine spiked sixty psychotropic drugs by LC-MS/MS with automated sample preparation unit.

High-sensitivity and Simultaneous Analysis of Psychoactive Drugs Using LC-MS/MS with Full-Automated Pretreatment System
In this study, we investigated the processing capability to analyze serum, whole blood and urine spiked sixty psychotropic drugs by LC-MS/MS with automated sample preparation unit. The results show the capability of the system for large sample set analyses with improved accuracy and precision by eliminating human error associated with manual sample handling.
A Fast LC-MS/MS Method for Quantitative Analysis of Five ¬-LactamAntibiotics in Human Plasma
A fast MRM-based method for quantitation of five ¬-lactam antibiotics tazobactam, cefepime, meropenem, ceftazidime and piperacillin in human plasma was developed. A simple sample pretreatment with protein crash by organic solvent was applied and a small injection volume of 2 μL was required due to the high sensitivity of the LCMS-8060 employed.

Measurement of Enzymatic Activities in Dried Blood Spots with On-line Solid Phase Extraction-LC-MS/MS System
In this application, a protocol developed at the Meyer Children's Hospital, Mass Spectrometry, Clinical Chemistry and Pharmacology Laboratory (Florence, Italy) was used to measure the enzymatic activity in dried blood spots (DBS) using an online solid phase extraction (SPE) – LC-MS/MS system.
Integration of Amino Acid, Acylcarnitine and Steroids Analysis in Single FIA/LC-MS/MS Platform
In this study, we present a strategy for performing both amino acids (AA)/ acylcarnitines (AC) and steroids analysis within a single LC-MS/MS platform. All compounds were extracted from only one dried blood spot. This system enables to automatically analyze 7 min in all target analytes in 2 injections.
Clinical Toxicology
A Novel Platform of On-line Sample Pretreatment and LC-MS/MS Analysis for Screening and Quantitation of Illicit Drugs in Urine
This platform, CLAM-2000 module coupled with Shimadzu LCMS-8040 was applied and evaluated for quantitation of 18 illicit drugs with 14 isotope-labelled internal standards. The method performance was evaluated on the linearity, accuracy, speci city and process ef ciency.
Screening Analysis of Highly Polar Doping Agents in Urine Using 2D LC-MS/MS
In this application news, we report the simultaneous analysis of highly polar doping agents including meldonium and adrenergic agents such as synephrine, norfenefrine, etilefrine, oxilofrine and octopamine using 2D LC-MS/MS.
15 Second Screening Analysis of Cyanide in Blood Serum Without Pretreatment
This article introduces a rapid careening method for detecting cyanide in blood serum that does not require pretreatment by utilizing the DPiMS-2020 and In-Source CID.
Quantitative Multi Target Screening (MTS) Using Liquid Chromatography-tandem Mass Spectrometry with MS/MS Library Based Identi¬cation for Forensic Toxicology
A MTS procedure for clinical and forensic toxicology screening was developed for a single LC-MS/MS method following a QuEChERS extraction of whole blood. This approach results in robust quantitation using MRM data and enables a higher degree of con dence in compound identi cation.
Analysis of Steroids and NSAIDs Using the Shimadzu LCMS-8050 Triple Quadrupole Mass Spectrometer
In this article, we introduce an accurate identi cation method for typical steroidal and non-steroidal anti-in¬ammatory drugs using multiple reference ion ratios, in addition to an example of high-sensitivity measurement.
Analysis of Carbon Monoxide in Blood
This article introduces an example of measuring carbon monoxide (CO) in blood, which is known as a toxic gas produced from the incomplete combustion of organic compounds. The barrier discharge ionization detector (BID) was applied to detect CO because of higher sensitivity compare to TCD.
