ORBO™ 23 2-HMP on Amberlite™ XAD®-2 (20/40), 120/60 mg sorbent tubes (W,W,W separators, O.D. × L 6 mm × 85 mm) contain two beds of the same selective adsorbent separated by glass wool or foam, for gas and vapor sampling. The dual-layer or two-bed construction of the tube allows for any sample breakthrough to be captured in the smaller back-up bed.

A method to sample and analyze chlorothalonil and dichlofluanid in greenhouse air was evaluated. Analysis was performed by gas chromatography with electron capture detection and gas chromatography-mass spectrometry. Solid sorbents such as Chromosorb 102, Porapak R, Supelpak-2, Amberlite XAD-2, Amberlite
A methodology is described for greenhouse air analysis by sampling fenhexamid, pyrimethanil, malathion, metalaxyl-M and myclobutanil in solid sorbents. Pesticides were determined by gas chromatography with NP Detector. The trapping efficiency of XAD-2, XAD-4, Supelpak-2, Florisil and C-18 at different

Elevated extracellular cGMP levels have been observed in various clinical conditions, and the analyte has been proposed as a diagnostic marker of cardiovascular as well as malignant diseases. However, the use of extracellular cGMP as a pathophysiological marker requires detailed
Endometrial hyperplasia is a precursor lesion of endometrial carcinoma. Clinical studies of endometrial hyperplasia have shown that levonorgestrel (LNG) is more therapeutically effective than medroxyprogesterone acetate (MPA). The present pharmacological in vitro study was performed to compare progestin effects on

The development of female steroid hormone-related neoplasms such as gynaecologic and mammary cancers is influenced by hormones administered exogenously. Hormonal contraceptives and hormone replacement therapy both affect the risk of developing cancers in the endometrium, cervix, ovarium, and mammary glands.
