A data processing system for a chromatograph, in which, when the inflection points in one of the front and rear parts of a peak divided at a peak top cannot be appropriately detected, a tangent to the peak is drawn at the detected inflection point, and an intersection point of the tangent and a baseline is detected. Furthermore, a point at which a perpendicular drawn from the peak top to the baseline intersects with the baseline is also detected. Then, the distance between the intersection points is calculated, and a value obtained by doubling this distance is adopted as a peak width. |
