LCMS-8060 Application - Developing a Chiral Amino Acid Analysis Method That Uses Column Switching (Japan)
Analysis of D-amino acids is susceptible to interference by a wide variety of peptides and amino compounds, and therefore requires high sensitivity and highly selective analysis methods for accurate measurement. Furthermore, conventional optical separation analysis of amino acids necessitated derivatization and long separation times of the amino acids. This article introduces a rapid analysis method that employs chiral columns to achieve high separation and high sensitivity and that dispenses with derivatization. This system uses two types of chiral columns alternately with high-pressure column switching valves (FCV) and allows fully automatic analysis of a wide range of D- and L-amino acids.

ICPMS Application - Analysis of Minerals and Harmful Elements in Formula Milk Powder Using ICPMS-2030
Formula milk powder is formulated to contain a good balance of minerals necessary for infant growth. Japan's Health Promotion Law includes stipulations on the essential mineral content, including calcium (Ca), iron (Fe), and copper (Cu), of food for special dietary use (e.g., formulated milk powder for infants) and requires the labeling of their content. Harmful elements like lead (Pb) have a negative effect on infant development, and require strict safety controls from raw materials to the finished product. We describe using Shimadzu's ICPMS-2030 inductively coupled plasma mass spectrometer to perform a simultaneous analysis of elements present in formula milk powder (National Metrology Institute of Japan certified reference material [NMIJ CRM]). In addition to being highly sensitive, the ICPMS-2030 uses a helium gas collision system that greatly reduces the spectral interference caused by argon and chlorine.

ICPMS Application - Analysis of Toxic Elements in Supplements as per USP 2232 Using the ICPMS-2030
The United States Pharmacopeia (USP) 2232 designates permitted daily exposure (PDE) levels for four elements for which toxicity is a concern in dietary supplements. PDE values need to be converted to concentrations when evaluating metallic impurities in formulations or their structural components. Compliance with these regulations is also obligatory for supplements imported to the U.S. from other nations. Here, we introduce a quantitative analysis performed on arsenic, cadmium, mercury, and lead in supplements using the Shimadzu ICPMS-2030 ICP mass spectrometer.

SFC/SFE Application - Improved Sample Pretreatment Using Offline Supercritical Fluid Extraction
Separation analysis using HPLC, SFC or GC requires a pretreatment step to ef ciently extract a target constituent from the sample in various forms (e.g., solid). Constituents are usually extracted from solid samples using dissolution or solid-liquid extraction methods. Dissolution methods can only be used when the sample is soluble in a given solvent, and they are dif cult to optimize depending on the analytical conditions. Solid-liquid extraction methods (e.g., Soxhlet extraction) are not suited to the pretreatment of multiple samples as they require considerable time for extraction and non-extraction (e.g., cleaning, preparation) operations. However, extraction methods involving supercritical uids can utilize the characteristics of supercritical uids (e.g., high solubility, permeability) to achieve the elution of a target constituent from a solid sample with high ef ciency and also allow automation during the extraction process. This article describes the utilization of the Nexera UC SFE pretreatment system, which increases the ef ciency of sample pretreatment for analysis.

GCMS-TQ8040 Application - Multi Pesticides Residue analysis in Ayurvedic cough Syrup by GCMS/MS using QuEChERS’ extraction method (India)
Ayurveda is a Sanskrit term, which means ‘science of life’. In India, Ayurveda has been long practiced for medicinal purpose. Majority of it’s preparations involve presence of plants, herbs etc. For the normal, disease-free growth of these plants and herbs, pesticides are widely used. Some of these pesticides can act as toxins to animals & humans when consumed even as residues. Hence, it becomes important to quantitate the pesticides at residual levels in orally consumed preparations, especially which involve plant materials such as Ayurvedic cough syrups. QuEChERS (Quick, Easy, Cheap, Effective, Rugged & Safe) method was used for extraction and clean-up of the sample followed by analysis using GCMS-TQ8040 Triple Quadrupole (GCMS/MS) system from Shimadzu Corporation, Japan.

GCMS-TQ8040 Application - Determination of pesticide residues in traditional Chinese medicinal materials Milkvetch Root (China)
In the process of cultivation of Chinese herbal medicines, it’s often threatened by variety of diseases, the yield and quality of medicinal materials are impacted directly which causing significant economic losses. In 1997 the national Traditional Chinese Medicine Bureau organized relevant units to carry out research on Chinese herbal medicine plant protection, the result of investigation shows that the medicinal plant diseases and insect pests prevention is the weak link for the production of Chinese herbal medicine. Plant diseases and insect pests of many types, bring severe losses. Due to the lack of knowledge about medicinal pesticide, misuse of pesticides is the prominent problem. The problem of pesticide residues in Chinese herbal medicine, a direct impact on human health, hinder the traditional Chinese medicine into the international market. In this paper, using the SHIMADZU three triple quadrupole GC-MS realized the determination of multiple trace pesticide residues in Milkvetch Root by instrument GCMS-TQ8040, the method has high sensitivity and good accuracy.

Nexera UC Appliccation - Analysis of Vitamin E in a Commercial Supplement by Offline SFE-SFC-PDA
Vitamin E, also called tocopherol is a fat soluble vitamin and an important chemical substance that exhibits an antioxidant effect, particularly in the human body. There are four tocopherols (α, β, γ and δ) that differ based on the number and position of methyl groups. The α-tocopherol exhibits the strongest antioxidant activity, and this is the tocopherol form found in most commercial supplements as vitamin E. Since it is highly fat-soluble, a quick and simple extraction method using supercritical fluid is expected to be applicable. In this article, we introduce a procedure for α-tocopherol pretreatment that uses supercritical fluid extraction (SFE).

LCMS-8030 Application - Improvement in Suppression of Carryover of Auto-Sampler for High Sensitivity MS Detector (Japan)
As the sensitivity of the mass spectrometer has been greatly improved, the carryover of the sample remaining in the auto-sampler has become the most significant factor determining the quantitative performance of the whole LC-MSMS system. Meanwhile, as the demands arise for faster speed and higher resolution of the analysis, the higher-pressure HPLC has become available from many HPLC venders. However, users sometimes experience carryover problem in higher-pressure system that they have not experienced with conventional HPLC system pressure. We have studied how the carryover performance is affected by the system pressure, and in this paper we report how we can improve carryover in a higher-pressure application.
