ATLAS prepared a program for measurements of production cross sections both of b‐hadrons and Onia in central proton‐proton collisions at new energy 14 TeV of LHC. Dedicated triggers based on muon, di‐muon or electron signatures are designed to accommodate large statistics with already first several months. Starting from semi‐inclusive measurements for very early stage exclusive channels will soon dominate measurements, allowing tests of QCD in Heavy Flavour sector already with 10 pb‐1. With larger statistics production polarization measurements are being prepared for J/ψ and Λb. It is expected that 30 fb‐1 collected at 1033cm-2 s-1 will allow specific measurements not accessible with limited statistics of Tevatron. In particular Λb polarization measurement can be achieved using Λb → J/ψ Λ decay. In J/ψ a polarization measurement will allow to confirm or exclude model predictions within large interval of transverse momenta.
