The column dimension is the same. The column is full of silica particles which can be modified to generate them non-polar. This really is finished by attaching extensive hydrocarbon chains (eight–eighteen C atoms) to its surface.
一套高效液相色谱装置。从左至右：一台恒流输液泵将两种不同种类的溶剂按照一定比例变化梯度输送至不锈钢结构的色谱柱。与溶剂混合的分析物则依次从色谱柱的另一端流出并流入吸收光传感器，以测定吸光度。
Sample injection — Soon after injection in to the cell stage, the sample travels with the cell phase in the injection issue to the head of your column.
Remedy: Within an HPLC system, guard columns are placed involving the injector and the analytical column, principally to safeguard the analytical column.
You should ensure you want to to acquire advertising and marketing and promotional e-mail messages about Thermo Fisher Scientific products and services.
The detector monitors the eluent because it exits the column. Unique detectors are used according to the compounds staying analyzed as well as required sensitivity.
高效液相色谱作为一种重要的分析方法，广泛的应用于化学和生化分析中，常用於醫藥品、化學、環保、生命科學、與食品工業的研究上。
High quality Examination of preclinical dose formulations for GLP and non-GLP toxicology reports. We conduct formulation sample Evaluation to assess stability, homogeneity, and to find out solubility issues.
The data that HPLC get more info can get consists of resolution, identification, and quantification of the compound. What's more, it aids in chemical separation and purification. The other apps of HPLC include things like
Soon after leaving the column, the person substances are detected by an appropriate detector and passed on as a sign for the HPLC program on the computer.
This may generate an here overall equilibrium equation which dictates the amount of A that should be affiliated with the stationary stage and the amount of A that will be affiliated with the cellular phase.
Leveraging substantial knowledge dealing with lots of tissue types, the DMPK workforce also supports tissue distribution scientific studies applying cold compounds.
High high-quality Assessment of preclinical dose formulations for GLP and non-GLP toxicology experiments. We carry out formulation sample Examination to evaluate steadiness, homogeneity, and to find out solubility troubles.
Then seeking similar posts with specified search phrases on Online search engines like yahoo (like Google Scholar) or databases (like PUBMED) will let you out a lot for selecting the subject. I want you a very good luck.
