About Pound-moles per day
The pound-mole per day (lb-mol/d) equals 453.59237/86400 ≈ 5.249×10⁻³ mol/s, used for daily material-balance reconciliation in US petroleum refineries and chemical plants. Process computer logs accumulate flow integrals as lb-mol/d; pipeline natural-gas custody-transfer accounting also uses lb-mol/d figures in US contracts. 1 lb-mol/d ≈ 5.249×10⁻³ mol/s = 453.59 mol/d.
About Femtomoles per second
The femtomole per second (fmol/s) equals 10⁻¹⁵ mol/s, the detection threshold of ultra-sensitive bioanalytical instruments. Modern nano-HPLC-MS systems and chip-based microfluidic biosensors detect enzyme reaction rates and protein-ligand binding kinetics at fmol/s throughput. Single-molecule fluorescence assays and electrochemical biosensors for early cancer biomarkers routinely operate at 0.1-10 fmol/s. 1 fmol/s = 10⁻¹⁵ mol/s = 60 fmol/min.
