      abstract     = {Two gas-phase formaldehyde (HCHO) measurement techniques, a
                      modified commercial wet-chemical instrument based on
                      Hantzsch fluorimetry and a custom-built instrument based on
                      fiber laser-induced fluorescence (FILIF), were deployed at
                      the atmospheric simulation chamber SAPHIR (Simulation of
                      Atmospheric PHotochemistry In a large Reaction Chamber) to
                      compare the instruments' performances under a range of
                      conditions. Thermolysis of para-HCHO and ozonolysis of
                      1-butene were used as HCHO sources, allowing for
                      calculations of theoretical HCHO mixing ratios. Calculated
                      HCHO mixing ratios are compared to measurements, and the two
                      measurements are also compared. Experiments were repeated
                      under dry and humid conditions (RH < $2\%$ and RH > $60\%)$
                      to investigate the possibility of a water artifact in the
                      FILIF measurements. The ozonolysis of 1-butene also allowed
                      for the investigation of an ozone artifact seen in some
                      Hantzsch measurements in previous intercomparisons. Results
                      show that under all conditions the two techniques are well
                      correlated (R2 ≥ 0.997), and linear regression statistics
                      show measurements agree with within stated uncertainty
                      $(15\%$ FILIF + $5\%$ Hantzsch). No water or ozone artifacts
                      are identified. While a slight curvature is observed in some
                      Hantzsch vs. FILIF regressions, the potential for variable
                      instrument sensitivity cannot be attributed to a single
                      instrument at this time. Measurements at low concentrations
                      highlight the need for a secondary method for testing the
                      purity of air used in instrument zeroing and the need for
                      further FILIF White cell outgassing experiments.},
