Abstract
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 (t) indicating (A) is included in a temperature range (T) that is either one of a predetermined temperature range Tand a predetermined temperature range T, 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 (t) indicating (D) is included in a temperature range (T), it is determined that the signal differential value (D) is a second peak. When X satisfies a condition [X≧predetermined threshold value], Y=Y/Yis calculated from an integral value (Y) of signal differential values in the temperature range (T) and an integral value (Y) of signal differential values in the temperature range (T). When Y satisfies a condition [1≦Y≦predetermined threshold value], it is determined that (D) is the second peak.
