All chemicals used were of
analytical grade, unless stated otherwise. Ultrapure water (18.25
MΩ cm) used throughout was produced by an ultrapure water purification
system (EPED-EQ-10T, Nanjing Eped Technology Development Co., Ltd.,
Nanjing, China). A wax printer (Xerox ColorQube 8580) was used to
print the pattern onto the filter paper (Hangzhou Fuyang Beimu Pulp
Paper Limited, Hangzhou, China). Potassium permanganate was purchased
from Tianjin Damao Chemical Reagent Factory (Tianjin, China). Ascorbic
acid and captopril (98%) used for preparing standard solutions were
purchased from Guangzhou Chemical Reagent Factory (Guangzhou, China)
and Shanghai Macklin Biochemical Co., Ltd. (Shanghai, China), respectively.
Vitamin C tablets and captopril tablets used as samples were purchased
from Jiangmen Hengjian Pharmaceutical Co., Ltd. (Jiangmen, China),
and Sinopharm Shantou Jinshi Pharmaceutical Co., Ltd. (Shantou, China),
respectively. Concentrated sulfuric acid was purchased from Xilong

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
