Passive sampling and/or extraction techniques in environmental analysis: a review
The main milestones in the development of passive techniques for sampling and/or extraction of analytes, and in biomonitors used in environmental analysis, are summarized in this review. Expand
Determination of nine high-intensity sweeteners in various foods by high-performance liquid chromatography with mass spectrometric detection
The proposed method has been successfully applied to the determination of the nine high-intensity sweeteners in drinks, yoghurts and fish products and is suitable for routine quality control analysis of foodstuffs. Expand
Analytical methodologies for determination of artificial sweeteners in foodstuffs
Abstract Artificial high-intensity sweeteners are used increasingly frequently for food production. The food industry tends to highlight beneficial aspects of their use (e.g., tooth friendliness,Expand
Advances in passive sampling in environmental studies.
Practical application of passive dosimetry in environmental analytics, including sampling of water, soil, air and other atypical media are discussed, and novel solutions and modifications of existing sampler designs have been presented. Expand
Simultaneous determination of nine intense sweeteners in foodstuffs by high performance liquid chromatography and evaporative light scattering detection--development and single-laboratory validation.
The trueness of the HPLC-ELSD method was satisfactory with recoveries ranging from 93 to 109% for concentration levels around the maximum usable dosages for authorised sweeteners and from 100 to 112% for unauthorised compounds at concentration levels close to the limit of quantification (LOQs).

The content of high-intensity sweeteners in different categories of foods available on the Polish market
The results indicated that foodstuffs under the study generally comply with European Union legislation in terms of sweetener content, but a few cases of food product mislabelling were detected, i.e. the use of cyclamate for non-approved applications. Expand
Organotin compounds in marine sediments
Organotin compounds are widely used in almost all sectors of industry. Antifouling paints, which were applied to ship hulls to protect from fouling organisms, are the main source of TBT and TPhTExpand
Determination of Non-Steroidal Anti-Inflammatory Drugs in Natural Waters Using Off-Line and On-Line SPE Followed by LC Coupled with DAD-MS
Two different procedures for simultaneous determination of six NSAIDs (diflunisal, diclofenac, fenoprofen, ibuprofen, naproxen and tolmetin) in environmental waters are described. Final analysis ofExpand
Retention behaviour of some high-intensity sweeteners on different SPE sorbents.
It was found that aspartame and alitame can be selectively separated from the mixture of sweeteners using formic acid-triethylamine buffer at pH 3.5. Expand
Speciation of mercury by ICP-MS after on-line capillary cryofocussing and ambient temperature multicapillary gas chromatography
An automated, small and easily mountable/demountable accessory based on a constant temperature multicapillary GC is proposed for time-resolved introduction of gaseous mercury species into an ICP-MS.Expand
