Immediately report any such damage to your vendor and the transport company. CIM® Disks are shipped in a suitable storage solution at room temperature. Upon arrival they need to be stored at +4 (39 °F) to +8 °C to (46 °F) until use. WARNING: Do not store the CIM® Disks below 0 °C (32 °F). ATTENTION: Occassionally, some color variation may be observed on CIM® housings. The variation in color does not affect neither the quality of the housing material nor the column performance. Optimization of HPLC System for Efficient Separations The set-up of the HPLC system is one of the crucial factors in achieving optimal performance from CIM® Disk Monolithic Columns. Since CIM® Disk Monolithic Columns are commonly used for gradient separations, the HPLC system should include at least two HPLC pumps connected via capillaries and a mixing tee to the injection valve or autosampler, a filling loop for the sample injection, a column, a detector, and a recorder or data acquisition system. 1 Each of these components has a direct influence on the separation quality when fast analyses are required. Capillaries: The inner diameter of the capillaries strongly affects the peak shape. Using smaller diameters results in sharper peaks, increases the quality of the separation, and raises the back pressure of the LC system. Small diameter capillaries also have smaller volume, thus reducing the total system dead volume. Capillaries with inner diameter of 0.5 mm or less are recommended. Back pressure: Check the back pressure of the system at a flow rate that is up to 2 ml/min higher than the flow rate that will be used during the actual work. It is advisable that the back pressure of the system alone is below 20 bar (2 MPa). Mixing tee: A low dead volume mixing tee, (e. g. 10 µl), should be used for fast gradient separations. This will improve the peak quality and resolution. Detector: To obtain an optimal performance from CIM® Disk Monolithic Column, the detector response time should be set to the lowest possible value – which is 0.1 s for most UV detectors. Acquisition rate: The acquisition rate depends on the analysis time. Typical analysis times in the case of CIM® Disk Monolithic Column is just few minutes. To obtain optimal resolution for separations of less than 1 minute, the acquisition rate should be 5 to 10 Hz. The HPLC system is now ready for fast analyses! PREPARATION OF CIM® DISK MONOLITHIC COLUMN FOR USE CIM® Disk Monolithic Column consists of a CIM® Disk (Figure 1), a housing (Figure 2) and a disk extractor (Figure 3). The chemistry of the disk is determined by the ring color. Nonporous Fitting Ring (b) Monolithic Matrix (a) Figure 3: Disk extractor Assembly of CIM® Disk Monolithic Column (Refer to Figure 2) 1. Unscrew one of the screw caps (e) from the housing. 2. Remove one of the retaining fittings (d). 3. Remove CIM® Disks from the container with a pincette and place it gently into the housing cylinder (c). Note: Up to 4 CIM® Disks of the same or different chemistries (e. g. ion-exchange and affinity) can be inserted into one housing cylinder (c). 4. Reinsert the retaining fitting (d) to fix the disk approximately in the middle of the housing cylinder (c). 5. Tighten both of the screw caps (e) by hand. 6. Connect the CIM® Disk Monolithic Column to the HPLC system preferably using PEEK fingertight fittings (1/16” OD UNF 10-32). The flow direction is not important due to the symmetrical design of the column. Equilibrating CIM® Disk Monolithic Column Before you begin working with the CIM® Disk Monolithic Column the product should be equilibrated and the flow characteristics and backpressure checked in accordance with the following procedure: 1. Wash the CIM® Disk Monolithic Column with at least 10 column volumes of the binding mobile phase (e. g. for ion-exchange chromatography a low ionic strength buffer) at one-half of the working flow rate. Note: Allow 2 column volumes to flow into a waste container. This will remove any small particles or air bubbles that may effect the detector cell. 2. Wash the CIM® Disk Monolithic Column with at least 10 column volumes of the eluting mobile phase (e.g. for ion-exchange chromatography a buffer containing 1–2 M NaCl) at one-half of the working flow rate in order to elute any bound components and impurities. 3. Finally, wash the CIM® Disk Monolithic Column with at least 10 column volumes of the binding mobile phase at a working flow rate. 4. The CIM® Disk Monolithic Column is now ready for use. Exchanging the Column Chemistry Figure 1: CIM® disk Disk Housing Cylinder (c) Screw Caps (e) Blind Fittings (f) One of the unique features of CIM® Disk Monolithic Column is the ability to quickly and easily exchange the monolith stationary phase. The exchange is performed as follows: 1. Stop the pumps and disconnect the column from the HPLC/LC system. 2. Remove both of the screw caps (e) and retaining fittings (d). 3. Remove the disk from the housing cylinder (c) using the disk extractor (Figure 3). 4. Place CIM® Disk in the labeled container with a suitable storage solution. 5. Insert the new CIM® Disk according to the assembly procedure (See above). Operating Conditions Figure 2: Housing (POM or PEEK) for the CIM® Disk Monolithic Column 1.
