Low-temperature analytical instruments require helium management strategies that preserve both cryogen supply and measurement integrity. Recovery systems are commonly summarized by annual retention, yet an annual percentage cannot show whether a laboratory can absorb refill surges, maintain enough reliquefaction headroom, control impurity-driven maintenance, and keep vibration-sensitive spectra and images stable. This paper asks whether a compact helium recovery installation can be considered analytically ready when its performance is judged through an event-buffered continuity envelope rather than by recovery rate alone. The dataset is organized as five operating windows: annual liquid-helium circulation, daily cryogen demand, refill-event gas capture, impurity and maintenance behavior, and instrument-side stability. The evaluated record contains 1,825 L annual liquid-helium use, 98.5 L annual loss, a 5 L per day daily load, more than 10 L per day liquefaction capacity, 4,677 L gas storage at 125 psi, a typical refill input below 2,100 L gas, more than 99.5% helium purity, 0.4% hydrogen, pressure fluctuation near plus/minus 0.01 psi, and retained scanning probe spectra and images. The event-buffered assessment shows that the system is ready for the documented 5 L per day analytical load because annual retention is 94.60%, steady liquefaction capacity exceeds demand by more than a factor of two, storage capacity exceeds a typical refill input by about 2.23-fold, and measurement evidence remains compatible with low-vibration spectroscopy. The same analysis identifies three boundaries: operation at about 10 L per day becomes a steady-capacity limit, one-half storage leaves only a narrow refill reserve, and hydrogen-dominated impurities require maintenance planning beyond routine purifier recovery. The conclusion is therefore specific to the operating envelope: the system is analytically ready for the documented single-instrument operating envelope, but scale-up requires added liquefaction capacity, storage reserve, or a different refill schedule.
