Although sensitive detection of nitrosamines using luminol chemiluminescence detection has been reported, the instrumentation is not commercially available (14). However, the development of analytical methods for nitrosamine detection is challenging due to high sensitivity requirements, complex matrices, and the large number and variety of samples requiring testing. National Library of Medicine Calibration curves of all three FDA listed nitrosamines displayed R 0.999, the S/N of the 5.0 ng/ml linearity standard were 10 and peak area ratio %RSD (n=6) at 5.0 ng/ml and 10 ng/ml is between 1.74% and 4.37%. N-nitrosamines (nitrosamines) are attracting increased attention because of their high toxicity and wide distribution. Testing for these residual solvents in pharmaceuticals requires highly sensitive analytical methods. To accurately quantitate NDMA in ranitidine using FE-HSGC-NPD method, the diluent was modified to include 100 mg/mL pyrogallol, 20 mg/mL diphenylamine, and 0.1% phosphoric acid in methanol, and the ranitidine HCl sample size was reduced from 50 to 2 mg. Taking low levels of nitrosamines is safe. There are approximately 1.13 billion people with hypertension (6) and over 463 million people with diabetes worldwide (7), and heartburn occurs in roughly 1.5 billion people on a weekly basis (8). The potential utility of this sensor for distributed air monitoring was demonstrated by integrating the sensor device into a commercial sensing node, which enabled online detection of NDMA at ppb levels. The LOD was 1 ppb for all three nitrosamines. All authors reviewed, edited, and approved the manuscript.
