1. 1. The effects of urine adulteration with oxidants before drug analysis with LC-HRMS and CEDIA

   Kandidat-uppsats, Uppsala universitet/Institutionen för medicinsk cellbiologi

   Författare :Anna Nilsson; [2022]
   Nyckelord :Drugs of abuse; Manipulation; Mass spectrometry; Narcotics; Tampering;

   Sammanfattning : In drug analysis, different kinds of immunoassays are often used as an initial screening for urine samples. The positive screening results are then followed by a confirmatory test, which consists of mass spectrometry methods to detect the drugs. The confirmatory tests are considered to be more resistant to manipulation than the screening tests. LÄS MER

3. 2. Identification of new emerging pollutants in surface water using suspect screening analysis and prioritisation strategies based on regulatory databases

   Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

   Författare :Agnes Krettek; [2017]
   Nyckelord :emerging pollutants; suspect screening; LC-HRMS; regulatory databases; surface water;

However, the existing target analysis methodology only allows the detection of a very small fraction of the substances present in wastewater samples. LÄS MER
