The application assessment of different programs was performed with equivalence tests for method transfer pro second-order derivative spectrophotometry. The digital second-order derivative spectra were calculated on different instruments; GBC Scientific Equipment Cintra 20 (Cintral v.2.6 and Spectral v.1.70 software programs) and Thermo Scientific Evolution 300 (VISIONPro software) were analyzed using the amplitude A/B ratio (A = 2D265,263; B = 2D263,261). Amplitude A/B ratio is the resolution parameter for derivative spectrophotometry prescribed in European Pharmacopoeia. The obtained values for A/B ratio were either very similar or significantly different among programs: 0.669 (Cintral v.2.6), 0.549 (Spectral v.1.70), 0.556 (medium indirect VISIONPro), 0.557 (one-step Savitzky–Golay 7 VISIONPro), 0.689 (two-step Savitzky–Golay 7 VISIONPro). Method transfer was possible between Spectral v.1.70 and VISIONPro (medium indirect and one-step Savitzky–Golay 7), but the values obtained in Cintral v.2.6 were not comparable to the other programs. The absorbance data exported from both instruments were additionally calculated in OriginPro8 which provided almost the same mean A/B values (0.627 Cintral v.2.6; 0.624 VISIONPro), confirming that the two instruments recorded the same zero-order spectra. The calculation of resolution parameter could be used for verification of program comparison, which would enable transfer between sender and receiver laboratory. The accordance between program algorithms was confirmed when acceptable differences for values of resolution parameter (A/B ratios) were achieved.

数字微分分光光度法通过不同计算机程序分辨率参数比较的方法转移评价

不同程序的应用评估是通过等效性测试进行的,方法转移亲二阶导数分光光度法。在不同仪器上计算数字二阶导数光谱;GBC Scientific Equipment Cintra 20(Cintral v.2.6 和 Spectral v.1.70 软件程序)和 Thermo Scientific Evolution 300(VISIONPro 软件)使用振幅 A/B 比(A = 2D265,263;B = 2D263,261)进行分析。振幅 A/B 比是欧洲药典中规定的衍生分光光度法的分辨率参数。获得的 A/B 比率值在程序之间非常相似或显着不同:0.669(Cintral v.2.6)、0.549(Spectral v.1.70)、0.556(中等间接 VISIONPro)、0.557(一步 Savitzky-Golay 7 VISIONPro),0.689(两步 Savitzky–Golay 7 VISIONPro)。Spectral v.1.70 和 VISIONPro(中等间接和一步 Savitzky–Golay 7)之间的方法转移是可能的,但在 Cintral v.2.6 中获得的值与其他程序无法比较。从两种仪器导出的吸光度数据在 OriginPro8 中额外计算,提供几乎相同的平均 A/B 值(0.627 Cintral v.2.6;0.624 VISIONPro),证实两种仪器记录了相同的零级光谱。分辨率参数的计算可用于程序比较的验证,这将实现发送方和接收方实验室之间的传输。当分辨率参数(A/B 比)值达到可接受的差异时,程序算法之间的一致性得到确认。70 和 VISIONPro(中等间接和一步 Savitzky–Golay 7),但在 Cintral v.2.6 中获得的值与其他程序无法比较。从两种仪器导出的吸光度数据在 OriginPro8 中额外计算,提供几乎相同的平均 A/B 值(0.627 Cintral v.2.6;0.624 VISIONPro),证实两种仪器记录了相同的零级光谱。分辨率参数的计算可用于程序比较的验证,这将实现发送方和接收方实验室之间的传输。当分辨率参数(A/B 比)值的可接受差异达到时,程序算法之间的一致性得到确认。70 和 VISIONPro(中等间接和一步 Savitzky–Golay 7),但在 Cintral v.2.6 中获得的值与其他程序无法比较。从两种仪器导出的吸光度数据在 OriginPro8 中额外计算,提供几乎相同的平均 A/B 值(0.627 Cintral v.2.6;0.624 VISIONPro),证实两种仪器记录了相同的零级光谱。分辨率参数的计算可用于程序比较的验证,这将实现发送方和接收方实验室之间的传输。当分辨率参数(A/B 比)值达到可接受的差异时,程序算法之间的一致性得到确认。从两种仪器导出的吸光度数据在 OriginPro8 中额外计算,提供几乎相同的平均 A/B 值(0.627 Cintral v.2.6;0.624 VISIONPro),证实两种仪器记录了相同的零级光谱。分辨率参数的计算可用于程序比较的验证,这将实现发送方和接收方实验室之间的传输。当分辨率参数(A/B 比)值达到可接受的差异时,程序算法之间的一致性得到确认。从两种仪器导出的吸光度数据在 OriginPro8 中额外计算,提供几乎相同的平均 A/B 值(0.627 Cintral v.2.6;0.624 VISIONPro),证实两种仪器记录了相同的零级光谱。分辨率参数的计算可用于程序比较的验证,这将实现发送方和接收方实验室之间的传输。当分辨率参数(A/B 比)值达到可接受的差异时,程序算法之间的一致性得到确认。分辨率参数的计算可用于程序比较的验证,这将实现发送方和接收方实验室之间的传输。当分辨率参数(A/B 比)值达到可接受的差异时,程序算法之间的一致性得到确认。分辨率参数的计算可用于程序比较的验证,这将实现发送方和接收方实验室之间的传输。当分辨率参数(A/B 比)值达到可接受的差异时,程序算法之间的一致性得到确认。
