Waters does not sell <2 micron chiral UPLC columns. However, this does not mean that you cannot use your ACQUITY UPLC system with chiral columns packed with larger (>3 micron) particles.
These types of separations often utilize normal phase solvents (e.g., hexane). This requires installation of the Hexane Tetrahydrofuran Compatibility Kit (PN 205000464). At this point, I suggest that you:
1) Visit this link:
2) Read the two attached literature pdf's
3) Contact your local Waters representative since the installation of this kit is best performed by someone from Waters
