摘要
The present invention provides a melting curve analyzing method that can automatically analyze whether or not a peak is present in at least one of two temperature ranges. A signal differential value (A) having a maximum absolute value is searched for among signal differential values at respective temperatures. When a temperature (t1) indicating (A) is included in a temperature range (T1) that is either one of a predetermined temperature range TH and a predetermined temperature range TL, it is determined that (A) is a first peak. Further, a signal differential value (C) that is a first signal differential value after the absolute value changed from decreasing to increasing and a signal differential value (D) having an absolute value that is greatest next to the absolute value of (A) are searched for. When X = (A - C)/(D - C) satisfies a condition [X predetermined threshold value] and a temperature (t2) indicating (D) is included in a temperature range (T2), it is determined that the signal differential value (D) is a second peak. When X satisfies a condition [X ≥ predetermined threshold value], Y = Y1/Y2 is calculated from an integral value (Y1) of signal differential values in the temperature range (T1) and an integral value (Y2) of signal differential values in the temperature range (T2). When Y satisfies a condition [1 ≤ Y ≤ predetermined threshold value], it is determined that (D) is the second peak.
