まとめ

洗浄中の標準 (SIR) は,個々の標準溶液の必要性を排除することによって分析を簡素化する新しい校正方法です. このテクニックは,幅広い分析レベルでの正確な定量化のために単一の標準濃度を使用します.

科学分野:

分析化学
インストルメンタル分析

背景:

従来の校正方法では,既知の濃度の複数の標準溶液を準備する必要があります.
サンプルのマトリックス効果は,精密な分析量化に干渉する可能性があります.

研究の目的:

洗浄中の標準 (SIR) と呼ばれる新しい校正方法を導入し,評価する.
正確で効率的な化学分析のためのSIRの適用性を実証する.

主な方法:

SIRは,サンプルを導入した後,すべての分析物質を含む標準溶液で計測器を洗浄することを含む.
正確な比率の決定のために2つのタイムスタンプの内部規格が使用されます.
ICP-OESは概念実証に使用され,他の液体流技術への可能性がありました.

主要な成果:

複合マトリックスと認定された基準材料では,分析物質の回収率は88%から120%であった.
相対的な標準偏差は,数パーセントの範囲で一貫して低い.
この方法は,低μgのL−1範囲での検出限界を達成し,四次元の分析量を定量化しました.

結論:

SIRは従来の多点校正曲線を必要としない.
この方法は,マトリックスマッチングの基準を必要とせずにマトリックス効果を修正します.
SIRは,様々な分析技術に対して,簡素化され,正確かつ堅牢な校正戦略を提供します.

Standard Solutions

555

Standard solutions refer to solutions with a precisely known concentration or composition. A primary standard is a highly pure, high molar mass, stable substance that is entirely soluble in water, the most commonly used solvent in analytical chemistry. The primary standard solution can be used to standardize secondary standards, which are substances with known concentrations but are less pure and stable. Standard solutions are essential for achieving accurate and reliable results in analytical...

Testing Water Quality

179

When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...

Handwashing II: Pre-procedure and Initial Procedure Steps

1.1K

The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail...

Handwashing I: Introduction and Types of Equipment

4.5K

Handwashing is hand hygiene with plain or antimicrobial soap and water to physically remove dirt, organic material, and microorganisms. However, it may not kill all microorganisms. The handwashing procedure requires a hand wash basin, liquid soap, paper towels, a domestic waste bin, and disposable nail cleaner as optional equipment.
Hand wash basins in clinical areas should have faucets that can be turned on and off without using the hands; that is, they should be non-touch or lever-operated....

Quality of Water

184

In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...
