analyze water for trace amounts methamphetamine by u3000 赛默飞ultimate 3000 液相分析水中痕量甲基苯丙胺（一）

Analyze the water for trace amounts of methamphetamine by U3000 (赛默飞Ultimate 3000 液相分析水中痕量甲基苯丙胺（一）)

Instrument Type: HPLC

In this paper, three methods for the detection of methamphetamine in water samples were established based on thermo Field Ultimate 3000 liquid chromatography platform. The LOD of methamphetamine was 10ng/mL by mass injection. The large volume injection method points out the direction for the subsequent development of online-SPE and LC combined method. The methamphetamine analysis method based on PFP column was developed, which provided a mobile phase compatibility scheme for the subsequent two-dimensional analysis of mass spectrometry detector

a fast costeffective gcfid method for determination adulterated milk fat

A fast and cost-effective GC-FID method for the determination of adulterated milk fat

Instrument Type: GC

The aim of this application note is to demonstrate the performance of the Thermo Scientific™ TRACE™ 1600 Series GC coupled to flame ionization detection for the assessment of milk fat authenticity according to the International Standard ISO 17678:2019 [IDF 202:2019] method.

AN73981: Determination of Chlorate and Perchlorate in Milk using Ion Chromatography-Mass Spectrometry

Instrument Type: ICMS

Chlorate and other oxychlorine species have been associated with inhibition of iodine uptake in humans and the formation of methemoglobin. Infants and young children are at high‐risk due to their greater dependency on milk products and higher consumption/body weight ratio. This method uses a Dionex™ IonPac™ AS20 column set, on a compact IC system (Thermo Scientific™ Dionex™ Integrion™ HPIC system) coupled with a Thermo Scientific™ ISQ EC™ single quadrupole mass spectrometer to quantify chlorate and perchlorate in milk with a simple sample preparation.

trace element analysis foods using tq icpms

Maximizing laboratory throughput: Robust and accurate analysis of trace metals in food samples with triple quadrupole ICP-MS

Instrument Type: ICP-MS

The measurement of potentially harmful substances including toxic metals in food has become a major topic of public interest in recent years. Therefore, the screening of food samples for food safety and nutritional labeling is an important task. The ICP-MS was operated using a single measurement mode (TQ-O2) to screen the entire mass range (lithium to uranium). In total, full quantitation of 32 elements were demonstrated in a variety of different foods.

AN73341: Determination of Sugars in Dairy Products using HPAE-PAD

Instrument Type: IC

This application notes demonstrates that ISO/DIS 22184 for sugars (galactose, glucose, fructose, sucrose, lactose and maltose) determination in dairy products can be executed with a Dionex CarboPac PA1-2mm column using a Dionex HPIC system.
