Heading 1

Letter from Ludovic Live, CEO of Affinité Instruments


This is our first newsletter since the start of the COVID-19 pandemic. During this period, many of our customers, including the team at Affinité, have experienced certain forms of hardship, both on personal and professional levels. I hope that we are finally seeing the end of the tunnel, and we can start to slowly put this global crisis behind us.


During this pandemic, we have also seen incredible progresses made in the area of life science research. In particular, the speed at which rapid tests and vaccines against the SARS-CoV-2 virus were developed has never been thought possible before. Affinité Instruments is proud to also have played a small role in enabling researchers around the world to participate in this challenging endeavour. The difficulties of accessing SPR equipment with CROs during this time also emphasized the necessity for researchers to have a portable SPR platform anytime, anywhere. Affinité Instruments has been able to and will continue to fill this SPR accessibility gap as part of our mission statement.


The Affiniteam is here to help as we enter into this new era of life science. We now offer assay development services for those who need immediate turnaround. In addition, we will introduce new robust SPR platforms in 2021 to make laboratory clinical testing simpler, faster, and more affordable. In the meantime, I wish you all the best. We look forward to continuing to harness the power of portable SPR together with you.

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.


Microfluidic cell

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.
