Hal's confession walk: the full-spectrum scan, the kind the Show uses
Normally they’re after steroids, endocrine synthetics, mild ’drines, when they test. The O.N.A.N.T.A. guy gave indications this one’ll be a full-spectrum scan. Gas chromatography followed by electron-bombardment, with spectrometer readings on the resultant mass-fragments. The real McCoy. The kind the Show uses.
Context
The testing apparatus rendered at full technical resolution. The routine scan hunts "steroids, endocrine synthetics, mild 'drines"; this one is "a full-spectrum scan. Gas chromatography followed by electron-bombardment, with spectrometer readings on the resultant mass-fragments" — "the kind the Show uses." The junior body is about to be interrogated with professional-grade instruments, the same machinery that polices pro tennis, reducing a person to a mass-spectrum of fragments. Governance of the athletic body ends in literal molecular analysis: you are what the spectrometer finds in your urine.
