Method detection limits (MDLs) have been determined for the newly regulated HON
(Hazardous Organic NESHAP (National Emission Standards for Hazardous Air Pollutants)) compounds, which
validate selected ion flow tube mass spectrometry (SIFT-MS) as an effective solution for measuring these toxic
volatile organic compounds (VOCs) and other environmental pollutants in ambient air, whether at the fenceline
or in a mobile setting. SIFT-MS offers unparalleled speed, sensitivity and ease of use for environmental
monitoring applications.
In this seventh part of " Conversations with Michael Dong," a series on fundamentals of HPLC in pharmaceutical analysis, LCGC International’s "Perspectives in HPLC" column editor explains why 2.1-mm i.d. columns are less preferred for pharmaceutical quality control.
Ultrahigh-performance liquid chromatography–quadrupole time-of-flight mass spectrometry (UHPLC–QTOF-MS) shows how soaking and cooking break down soybean fats.
Nicolai Zederkopff explores chromatography’s role to help implement the maximum tolerable level (MTL) framework for food adulteration to translate analytical results into compliance decisions.
Franz Berthiller (BOKU University, Austria) discusses a multilaboratory study that used retention index markers to align mycotoxin liquid chromatography–mass spectrometry (LC–MS) data.
A QuEChERS/ultrahigh-performance liquid chromatography and high-resolution mass spectrometry (UHPLC-HRMS) method tracks 23 plant toxins in cereals and spices. Michele Suman discusses the method with LCGC International.
