P4SPR Maintenance Tips
Rinsing before and after each run
Before a run, once the sensor and microfluidic cell are secured, inject 1mL of deionized water into each injection port to condition the system. After a run, inject 1 mL of deionized water into each injection port to rinse the system. Then, purge the tubing with air to remove excess water.
If the microfluidic cell is to be re-used for future runs, rinse the engraved channels with DDI and dry before storage. Examine for any wear and tear before each re-use of the microfluidic cell.
Wear gloves for all manipulation of the sensor. Ensure that the sensor is taken out of the pack without touching the longer ends and the gold-coated surface. If visually, one of the longest ends looks obstructed, use 100% isopropyl alcohol to wipe the sides in order to remove any residues. Do not physically try to wipe clean the surface. Damaging the surface will impact your experimental data.
Tip of the day!
Keep bubbles to a minimum before injection. Gently tap on the syringe to remove bubbles before inserting syringe into the injection port to avoid bubbles during analysis.
