Ionic Liquid Stationary Phases in Gas Chromatography: Fundamentals, Recent Advances, and Perspectives

Online fully automated SPE‐HPLC‐MS/MS determination of ceftiofur in bovine milk samples employing a silica‐anchored ionic liquid as sorbent

“…Ionic liquids (ILs) have physical and chemical characteristics that can be adjusted according to changes in their structure to be employed as SPE sorbents aiming the pretreatment of contaminated samples of various types of analytes . These materials present a variety of favorable properties and immense applications when compared with commercial phases (Silica, C8, C18, HLB, NH 2 ) such as high thermal stable, nonvolatile and nonflammable, low vapor pressure and low cost of synthesis, high yield; good extraction ability for organic and inorganic compounds and reduces the extraction of interferents present in the matrix .…”

Analysis of essential oils and fragrances with a new generation of highly inert gas chromatographic columns coated with ionic liquids

“…The Grob test [23] consisting of a mixture of decane (1), undecane (2) or dodecane (3), 1-octanol (4), methyl decanoate (5), methyl undecanoate (6), methyl dodecanoate (7), 2,6-dimethylphenol (8), 2,6-dimethylaniline (9), dicyclohexylamine (10), 2-ethylcaproic acid (11) benzyl benzoate (CAS: 120-51-4), 28: benzyl salicylate (CAS: 118-58-1), 29: benzyl cinnamate (CAS: 103-41-3). They were solubilized in toluene at a concentration of 500 μg/l.…”

“…This article also lists a number of other reviews describing developments, chromatographic properties and applications to specific fields of several ILs and PILs in GC and MDGC appeared over the past decade. Over the last two years, other reviews concerning IL applications in GC have been published by Hantao et al [2], Kulsing et al [3] and Sun et al [4].…”

“…True quantitation was carried out by external calibration with the pure standards; these analyses were also used to evaluate analytical performances in terms of analyte repeatability and intermediate precision and R 2 to assess consistency of column behavior over time. The R2…”

Ionic Liquid–Liquid Chromatography: A New General Purpose Separation Methodology

“…However, ammonium and phosphonium cation ionic liquids can be used over the whole 200-to 800-nm range of modern UV-Vis spectrophotometers. Anions (such as chloride) can also be used over the 2005 [52] 2006 [53] 2007 [54] 2007 [55] 2007 [56] 2008 [24] 2008 [57] 2009 [58] 2010 [59] 2011 [60] 2012 [61] 2014 [62] 2016 [63] The use of ionic liquids in capillary electrophoresis and related technology 2004 [64] 2006 [65] 2008 [66] 2009 [67] 2013 [68] 2014 [69] 2016 [63] The use of chiral ionic liquids in chromatography 2005 [70] 2008 [71] 2008 [72] 2012 [73] 2014 [74] The use of ionic liquids in CCC 2008 [24] 2013 [75] The use of ionic liquids in GC 2009 [76] 2009 [77] 2011 [78] 2014 [79] 2014 [80] 2016 [81] 2016 [82] The use of ionic liquids in HPLC 2006 [83] 2009 [84] 2011 [85] 2012 [86] 2012 [87] 2015 [88] full 200-to 800-nm range, but anions such as triflate or bis{(trifluoromethyl)sulfonyl}amide absorb light at wavelengths below 250 nm. Coloured impurities in the ionic liquid can also affect the performance of the UV-Vis detector, but these can be removed by filtering the ionic liquid through charcoal [...…”
