I would really like to enroll in newsletters from Sartorius (Sartorius AG and its affiliated corporations) centered of my personalized pursuits.
内部にカラムを収納して加熱あるいは冷却を行い、カラムの温度を制御する装置。カラムヒーターとも称する。
전자를 '고정상', 후자를 '이동상'이라 부르며 크로마토그래피에서는 분석자는 고정상과 이동상의 조합에 의해 분석물의 분리를 제어할 수 있게 됩니다.따라서 분석물, 고정상, 이동상, 세 가지 특성의 이해가 크로마트그래피에서 매우 중요합니다.
Compatibility: The solvent shouldn't respond Using the analytes or degrade the sample matrix. Seek advice from basic safety data sheets (SDS) for compatibility data.
物質にエネルギーを与える（励起）ことにより発光する（蛍光）性質を利用した検出器。一般に選択性が高く高感度で、物質に特異的な検出が可能。蛍光する性質を持たない物質については、その物質を標識することにより検出が可能になる。
Fluoxetine is another name for that antidepressant drug Prozac. The resolve of fluoxetine in serum is a crucial Component of checking its therapeutic use.
混合物で構成される試料を分離する。一般にステンレス製の筒の中に、微細な真球状の多孔質シリカゲルをアルキル基等で修飾した物を充填して用いる。分取目的であれば、粉砕シリカゲルも用いられる。
2nd, a number of the compounds within the serum may possibly take in way too strongly into the stationary stage, degrading the column’s performance. Lastly, While an HPLC can independent check here and evaluate elaborate mixtures, an Evaluation is difficult if the number of constituents exceeds the column’s peak potential.
The figure beneath displays the calibration curve and calibration equation to the list of external benchmarks. Substituting the sample’s peak region to the calibration equation presents the focus of caffeine during the sample as ninety four.4 mg/L.
移動相としては、カラムや装置に悪影響を与えない範囲で各種の溶媒が使用される。水や塩類の水溶液、アルコール類、アセトニトリル、ジクロロメタン、トリフルオロ酢酸などが用いられる。相溶性のある（互いに混じり合う）溶媒を混合して使用する場合が多い。
The HPLC column properties the stationary stage, a critical aspect for separating analytes. Deciding on the correct column is crucial:
It's important for laboratory staff to get a elementary knowledge of HPLC just before applying it to analyze compounds properly and guarantee trustworthy results.
Stream amount: Move rate adjustment influences how immediately analytes move through the column. check here An best stream amount balances separation performance with Examination time.
Flow amount troubles: Flow level straight affects peak shape. A circulation amount that's as well high can lead to broader peaks due to a lot less conversation between analytes and also the stationary phase.
