Solid-phase extraction with strong anion-exchange columns for selective isolation and concentration of urinary organic acids.
Clin. Chem. 34(6) , 1077-83, (1988) This is a new method for isolating and concentrating urinary organic acids before gas chromatography--mass spectrometry. Sulfate and phosphate anions are removed by precipitation with Ba(OH)2, and the urine pH is adjusted to 8-8.5. The sample is then applied ... |

Sulphate removal from sodium sulphate-rich brine and recovery of barium as a barium salt mixture.
J. Environ. Sci. Health. A. Tox. Hazard. Subst. Environ. Eng. 48(8) , 933-8, (2013) Sulphate removal from sodium sulphate-rich brine using barium hydroxide and recovery of the barium salts has been investigated. The sodium sulphate-rich brine treated with different dosages of barium hydroxide to precipitate barium sulphate showed sulphate re... |

Reaction of phosphorylated and O-glycosylated peptides by chemically targeted identification at ambient temperature.
J. Biomol. Tech. 15(4) , 296-304, (2004) Conditions for carrying out chemically targeted identification of peptides containing phosphorylated or glycosylated serine residues have been investigated. Ba(OH)2 was used at ambient temperature to catalyze the beta-elimination reaction at 25 degrees C. Nuc... |

Increasing the sensitivity of microfluidics based immunoassays using isotachophoresis.
Analyst 139(18) , 4564-71, (2014) We have developed a microfluidic device that enhances the sensitivity of protein immunoassays by preconcentrating the protein sample using isotachophoresis (ITP). Two approaches were followed to study the sensitivity gain achieved that way. The first approach... |

Barium hydroxide lime turns yellow after desiccation.
Anesth. Analg. 101(3) , 748-52, table of contents, (2005) Ethyl violet is added to carbon dioxide absorbents and normally serves as an indicator of absorbent exhaustion. During the course of several prior studies of anesthetic breakdown, we noted (but did not publish) that barium hydroxide lime (BL), but not soda li... |

Isolation of bicarbonate from equine urine for isotope ratio mass spectrometry.
Isotopes Environ. Health Stud. 43(4) , 267-73, (2007) Sodium bicarbonate administration to horses prior to competition in order to enhance the buffer capacity of the organism is considered as a doping offence. The analysis of the isotopic composition of urinary bicarbonate/CO(2) (TCO(2)) may help to identify an ... |

Sevoflurane breakdown produces flammable concentrations of hydrogen.
Anesthesiology 106(1) , 144-8, (2007) Fires, explosions, and extreme heat production may occur when sevoflurane reacts with desiccated barium hydroxide lime. The identity of the flammable gas has not previously been published, although carbon monoxide, methanol, formaldehyde, and methyl formate h... |

Evaluation of barium hydroxide treatment efficacy on a dolomitic marble.
Ann. Chim. 91(11-12) , 813-21, (2001) The Arch of Peace, by Luigi Cagnola, is one of the most famous neoclassical monuments in Milan. It has been subjected to conservative intervention in 1998. In the present paper the efficacy of the consolidation by means of barium hydroxide has been evaluated.... |

[Hydrolysis of primary amide groups in Asn/Gln-containing peptides].
Bioorg. Khim. 26(6) , 403-10, (2000) Peptides Boc-Ala-Asn/Gln-OH and Boc-Asn/Gln-Ala-OH were saponified with barium hydroxide to corresponding Asp/Glu-containing peptides. Under the conditions of saponification, Boc-Asn-Ala-OH additionally afforded Boc-Asp-OH, isopeptide Boc-Asp(Ala)-OH, and Boc... |

[Various reactions of sevoflurane with the individual components of soda lime].
Anaesthesist 46(12) , 1071-5, (1997) The various components of commercial soda lime (sodium hydroxide, potassium hydroxide, calcium hydroxide, barium hydroxide) were studied in terms of their reactivity with sevoflurane at its boiling point (59 degrees C). A simple closed system, a reflux cooler... |
