TABLE II.

Ratios of particle concentration for tests with monodispersed aerosols.

Test Aerosol Composition	d_DMA	Concentration Range^*	r_n,SMPS = C_DM/C_SMPS	r_{n, CPC} = C_DM/C_CPC
NaCl	30	L	0.93	0.78
		M	1.17	0.98
		H	-	-
	100	L	0.81	0.85
		M	0.96	0.94
		H	0.89	1.13
	300	L	1.30	1.86
		M	2.26	1.84
		H	2.27	1.55
Metal	30	L	1.58	0.99
		M	1.67	1.19
		H	1.58	1.35
	100	L	0.86	0.91
		M	1.05	1.12
		H	1.01	1.16

Concentration ranges are: low (L, <10³ particles/cm³), medium (M, 10³–10⁴ particles/cm³), and high (H, >10⁴ particles/cm³)
