2020年12月22日 · About Us. LIGHTHOUSE draws on its years of innovation and expertise to bring you top-of-the-line, personalized equipment to keep your products, and by extension patients, healthy and safe. We introduced laser-based headspace analysis into the pharmaceutical industry in 2000 with the help of funding from the Food and Drug Administration.
2019年9月19日 · Container closure integrity testing (CCIT) by laser-based headspace oxygen can be performed for samples with an air headspace for the detection of both small (=20 micron) and large (0.5-2 mm) defects, evaluating the container closure integrity (CCI) of a sample at any point in the product-package life cycle. This article will discuss developing and validating a CCI

2022年4月12日 · 3. You can’t reuse the cap of the headspace vials since it is damaged when removed. The cushion (septa) of the vials, on the other hand, you may use only two or three times. You may pull each vial’s sample only once. Otherwise, the sample will be incorrect, and the amount of sample will diminish.
Hi chemist123, For minimum volume, there is really none and is sample dependent, I have run as little as 5ul in a volume. Maximum for a 20ml vial is 75% of the vial height (approx 15ml) , for a
2007年8月24日 · Headspace sample stability can only be demostrated when the matrix and analytes are carefully and exactly defined. Since I worked with different amounts of analytes and different matrices it was better to use concentrated standards which were then diluted and checked against fresh standards to determine std stability prior to std preparation.
2011年10月1日 · Headspace sampling (HS) keeps sample residues from entering the GC inlet by holding the entire sample matrix in a vial while transferring volatile components into the GC inlet and column. Nonvolatile contaminants remain behind in the headspace vial and do not accumulate in the inlet or the column. Chromatographers generally divide headspace

2011年2月16日 · by mac » Tue Feb 15, 2011 9:21 pm. Using the agitation increases the response of volatiles in your sample as more are realised into the headspace. This is especially useful
The 20ml precision threaded headspace vial is used for the threaded vial (20ml) and magnetic screw cap of CTC and TriPlus autosampler. 3. It is convenient to use and does not require any additional tools such as capper and decapper. 4. The sample is available on site Transfer, no need to transfer samples in the laboratory.
