関心があるアプリケーション

Dropping point of lubricating grease
The dropping point of a lubricating grease is the specific temperature at which a sample becomes fluid to form a drop that falls from a standardized dropping point cup.
Cloud Point of Non-ionic Surfactants
Cloud Point (CP) of non-ionic surfactants is highly influenced by addition of ionic surfactants as well as electrolytes. This provides scope for tuning CP depending on the prerequisites of the applications. In present study, trends in CP value of TergitolTM NP-10 (Nonylphenol ethoxylate) with addition of ionic surfactant (Sodium Dodecyl Sulphate) or electrolyte (potassium chloride) is evaluated. We use a MP80 instrument for fully automated CP determination.
沸点を利用したeリキッド(電子液体)の品質管理
このアプリケーションノートでは、電子タバコリキッド(ニコチンの有無にかかわらず)およびプロピレングリコールの沸点を決定する方法をについて説明しています。
同時ビデオ観察による相転移の融点測定
融点は間違いなく、材料の特性評価に最も頻繁に使用される熱値です。この事実に加え、融点測定の要件がますます高まっていることが、メトラー・トレドが全く新しいシリーズの開発を決定した2つの主な理由でした。新しいExcellence融点システムにより、従来の融点測定装置では測定できなかった物質を分析できます。
Slip Melting Point of Ghee Samples
Slip Melting Point (SMP) is an important parameter for monitoring the quality of ghee samples. The technique is faster and selective for characterization of such samples with composite mixtures and which do not have a sharp melting point. MP80 offers fully automated SMP detection, based on camera image analysis. This SMP detection technique is in compliance with the AOCS Cc 3-25 and ISO 6321 standards.
沸点を利用した電子液体の品質管理
プロピレングリコールなどの電子液体成分の品質は、沸点(BP)などの物理的特性(液体から気体への相転移が進行する物質固有の温度)を調べることで保証できます。BPは、気化(または沸騰)を誘発するために電子液体混合物を加熱する必要がある温度を決定するためにも使用できます。
化粧品の滴点試験
滴点試験により、液化した物質の液滴が標準化されたカップの開口部から重力によって逃げる材料固有の温度を定義します。
物質の沸点測定
化合物の沸点(BP)は、物質の同一性に関する有用な情報を提供します。未知のサンプルの測定値を基準値と比較して、サンプルの同一性を判断できます。この熱物性に関する知識は、製品安全データシート(MSDS)に必要です。
FMVVS No.116(DOT)に準拠したブレーキオイルの沸点測定
ブレーキング中、摩擦から発生する熱がブレーキシリンダーを暖め、ブレーキフルードの温度を上昇させる可能性があります。ブレーキオイルの沸点(BP)を超えると、ブレーキオイルに蒸気の泡が形成され、液体とは異なり圧縮可能です。これは、ブレーキシステムの性能に影響を与えます。したがって、特にブレーキによって発生する高温にさらされる場合は、ブレーキオイルが沸点を下回ることが重要です。
クルクミン(秋ウコン色素成分)の融点測定
このアプリケーションノートでは、食品業界で黄橙色で使用されるクルクミンの融点を測定するための詳細な方法について説明します。
界面活性剤の曇点測定
曇点(CP)は、水溶性界面活性剤(エマルジョンであれ分散液であれ)の信頼性の高い品質管理パラメータです。CPの測定は、処理された材料の最適な動作温度を決定する上で非常に重要です。
融点測定のための豊富なメソッドプログラミング
Excellence 融点測定システムの柔軟なメソッドプログラミングの異なる温度セグメントを使用することで、サンプルの分解やその他の化学反応を最小限に抑え、サンプルの完全性を維持します。これらの方法は、日本薬局方(JP<2.60>)および米国薬局方条約規則(USP<741>クラスIa物質に完全に準拠しており、時間を節約し、効率を最大化します。
ISO 6321に準拠したパーム油の上昇融点測定
パーム油およびパーム油誘導体の品質管理手順は、製品が食品および医薬品の規制への準拠が求められます (ISO 6321など)。これらの規制は、パーソナルケアや化粧品を製造する企業にも適用され、その多くはハラール、コーシャ、FDAの認定を受けていることがよくあります。品質検査では、スリップ融点(SMP)技術がよく使用されます。
AOCS Cc 3-25に準拠した口紅の上昇融点を確認する方法
製品は食品および医薬品規制を満たさなければならないため、口紅の品質管理手順は十分に確立されています(例:AOCS CC 3-25)。口紅は摂取される唯一の化粧品であるため、成分と製造プロセスに厳しい規制が課せられています。このような制御の例は、スリップ融点(SMP)の決定に基づいています
コレステロールの融点
このアプリケーションノートでは、Covid-19ワクチンの主要成分であるコレステロールの融点を測定するための詳細なスキームを提供します。
ピッチの軟化点評価
このアプリケーションノートでは、冶金コークスの製造中に副産物として得られる光沢のある黒色残渣の軟化点を決定するためのソリューションを提供します。
リップクリームの上昇融点測定
このアプリケーションノートでは、鋭い融点を持たないリップクリームサンプルのスリップ融点を検出するための系統的なスキームを提供します。
ノニルフェノールエトキシレート (NPE) 試験における曇点
ノニルフェノールエトキシレート(NPE)は、工業用洗浄製品、プロセス、農業用配合物、塗料に広く使用されている界面活性剤のカテゴリーで構成されています。水溶性NPE界面活性剤の場合、曇点は品質管理試験の信頼できる指標です。
食用油脂の滴点測定
食用油脂の滴点は、定義された試験条件下でオリフィス付きの標準化されたカップから落下する滴を形成するためにサンプルが流体になる特定の温度です。
