Purification services
Outsource your clean-up processing step to us to make use of our long experience in the field of preparative clean-up, eg by fractionation chromatography or selective retention or adsorbtion.
CLEAN-UP SERVICE
Redstone Separations clean-up service
- A large number of separation materials are available in-house to choose the most promising resins
- For purifications with higher selectivity demand: tailored resins can be developed and provided.
SUPPORT
Support in challenging separation projects
With a long experience on the design and use of both standard and tailor-made separation materials we can help you to get to the next step of your separation tasks.
- Separations of your sample into fractions
- Processes to remove undesired components
- Processes to enrich valuable target compounds
Redstone Separations AB has extensive experience in the field of resins and has a large number of TEMIZ™ resins available for evaluations. For your separation challenge we can identify, optimize or design the best suitable resin for your purification project. We will support you in the various steps:
Evaluation phase
- Evaluation of your separation project and ways forward
- Identification / Design of best separation materials
- Work out the best separation process
- Separations can be evaluated in a column or in suspension
Scale-up phase
- Consultations on the separation process
- Consultations on the process equipment
- Support for transfer to industrial scale
PRINCIPLES
Principle of fractionation
A mixture of compounds can be separated (into its components) by the use of chromatography
- Choose appropriate resin / separation material + column geometry
- Load mixture on column
- Elute with solvents / salts / additives to desorb the various compounds
- Collect eluted compounds in separate containers; clean / regenerate column
- Fractions (Blue, Red, Green, Grey) available in separate containers
Principle of selective separation
A target compound can be selectively removed from a mixture of compounds by the use of a selective separation material
- Choose appropriate resin / separation material + column geometry
- Load mixture on column
- Let the majority of compounds pass without retention
- Elute the bound compound(s) in a separate container; clean / regenerate column
- “Cleaned” fraction (Pink) and target compound (Brown) isolated into separate containers
HOW IT WORKS
Steps of custom purification project
- Customer sends process solution/material to be purified to Redstone Separations AB in Sweden
- Redstone conducts small-scale purification studies
- Outcome of the initial purification study is discussed with customer
- If the process parameters are met, the purification is conducted at larger scale at Redstone
- Redstone delivers purified compound back to the customer
