The Agilent 8700 LDIR chemical imaging system has its own community, a members-only group for discussions and resources on methods, libraries, microplastics, and all things LDIR – Join the LDIR Community!
** Molecular Spectroscopy Announcements ** …
The Agilent Community, an online customer support and forum space, has expanded to include two specialized user groups focusing on transmission Raman spectroscopy and the 8700 LDIR for microplastics analysis. These groups allow for dedicated spaces for…
Chemical imaging has a new name: LDIR (Laser Direct Infrared Imaging)
I absolutely love infrared microscopy. Distinguishing between seemingly identical materials using light we cannot even see feels nothing short of a fantastic trick. This isn’t a trick…
Reports of the omnipresence of microplastics have mainly focused on their presence in the environment, but there is a growing interest in investigating the health impacts of microplastics. Many people would assume that infants' exposure to microplastics…
To achieve accurate and reproducible analysis of microplastics, certain practical aspects should be considered. In this on-demand webinar, we highlight microplastic sample preparation in various matrices and examine best practice for performing accurate…
Hi, I am a new user of LDIR and I just start doing some tests with microplastic samples. After inserting the sample, I performed a spectral survey for a point, but then I don't know hot to compare it with a library. There is a list of libraries I can…
There are many challenges in the fast-developing field of microplastic analysis. In this webinar, we will hear from two speakers addressing quite different challenges, but nonetheless, challenges faced by many. The first speaker, Dr Gbotemi Adediran from…
Microplastics are everywhere. They have been discovered in all areas of the natural environment, within the food chain, and in aquatic organisms, animals, and humans. Clearly, there is an urgent need to identify microplastics in the environment and to…
My Green Lab’s ACT labelling - Accountability, consistency, and transparency
There are many reasons why I like working at Agilent. One of those is Agilent’s progress towards sustainability and ultimately a zero-carbon future. Collaborating with My Green…
