filtered, aqueous 3 mM hydrochloric acid at a  concentration of 66.3 µM. 0.5 mL/ampoule  CRM-Zero-Mus is a mussel tissue (Mytilus edulis) matrix  CRM intended for use as a negative control for the  analysis of paralytic shellfish toxins (PST), domoic acid  (DA) and its isomers, okadaic acid (OA) and  diniphysistoxins (DTX), azaspiracids (AZA), yessotoxins  (YTX), pentenotoxins (PTX) and gymnodimine (GYM).  CRM-Zero-Mus is not suitable as a negative control for  spirolides (SPX) and pinnatoxins (PnTX) because these  toxins are present, albeit at very low levels. 8 g/bottle  1  CRM-ASP-Mus-d is a thermally sterilized homogenate of  mussel tissue  (Mytilus edulis)  contaminated with domoic  acid (DA) and some of its isomers. Each unit contains  two ~4 g of the homogenate. The DA concentration is  49 µg/g. Used in conjunction with CRM-DA-f, this CRM  will assure the reliability of your domoic acid analyses.  (2) 4 g bottles  3  CRM-AZA-Mus is a certified reference material (CRM)  prepared from naturally contaminated mussel tissues  (Mytilus edulis)  containing azaspiracids. CRM-AZA-Mus  is designed to assist the analyst in assessing entire  analytical methods used to monitor AZA toxins in  shellfish tissues. Each bottle contains ~8 g of mussel  homogenate with AZAs at levels appropriate for  analytical testing. The certified values for CRM-AZA- Mus are: AZA1 - 1.16 μg/g, AZA2 - 0.273 μg/g and  AZA3 - 0.211 μg/g.  8 g/bottle  1  Organophosphorus Compounds  100 μg/mL each in acetonitrile, 1 mL/ampul  Acephate (30560-19-1)  Carbaryl (Sevin) (63-25-2)  Dicrotophos (141-66-2)  1  August 2020 EN-c4f_annexiitechspeciiitechoffer_en.docx  EN-c4f_annexiitechspeciiitechoffer_en.docx Page 23 of 76
