4. Analyze the filtered sample by HPLC. Cosmospin Filter Components : Sample Reservoir Sample Collection Tube How to use : 1. Insert a Cosmospin sample reservoir into a Cosmospin sample collection tube. 2. Add a sample into the Cosmopsin sample reservoir. 3. Close the sample collection tube cap and centrifuge. 4.
To separate large biomolecules, such as peptides and proteins by reversed phase (RP), the pore size of the support particle is an important consideration. Because retention can be strong and the mobile phase contains an organic modifier, RP is usually avoided with proteins that are needed to be recovered in their active forms.
Tosoh Bioscience offers reversed-phase columns for
High Performance Liquid Chromatography (HPLC) is an analysis technique used for separation and quantification of small molecules and polymers. HPLC is the method of choice for testing complex mixtures containing non-volatile and semi-volatile organic compounds such as polymer additives , active pharmaceutical ingredients (API’s), and impurities.
The minimum required volume in the sample vial is vary instrument to instrument and is completely based on the auto sampler, in particular how long needle will insert into the sample vials.
Apr 16, 2019 · For example, polymer marker bands used on balloon catheters are cut from thin-walled polymer tubing with high loadings of tungsten filler to enhance visibility under fluoroscopy. This material is too heavy to retain shape during free-form extrusion and requires support by a mandrel of the inside diameter.
Microvolume inserts are sold in both glass and polyproylene materials. Polypropylene inserts are recommended for pH-sensitive samples, greater solvent compatibility, biological samples, and ionic samples becasue of the material′s inertness.
Several styles are offered including flat bottom, concial inserts with a top spring or a bottom spring, and concial without springs.
Figure 2. Chromatogram of a polymer under investigation. This separation is based on a slight difference in hydrophobicity between the mono and difunctional species. Figure 2 shows the chromatogram of a polymer under investigation. In this case, the minor component is not detected, illustrating that this HPLC technique can be used
The sample preparation method for normal and reversed phase analysis is as follows: Fundamental theory * The sample should be dissolved in the eluent to be used and filtrated with 0.45μm disposable filter. Then, it should be injected into HPLC system about 10 to 50μL.
Thermo Scientific Transcend Multichannel Systems for highest LC-MS throughput and a minimum of sample preparation efforts.
