Remarks:
Pig liver (CTC free)(Chlortetracycline free) The material consists of lyophilised material equivalent to approximately 5 g of fresh tissue in sealed glass vials *** For more information see https://crm.jrc.ec.europa.eu/p/BCR-695 *** Additional keywords: CTC, veterinary drug residues

Intended Use:
The blank material can serve to establish recovery-values for a method of analysis at various levels of contamination, through spiking of the material. It can also serve to check the specificity of a method for chlortetracycline by providing an effective blank, and to investigate the limit of detection.

Remarks:
The reference samples are (30*30*5) mm steel coupons coated with a diamond-like carbon coating (DLC) applied by plasma-assisted chemical vapour deposition. The coupons are distributed in a reusable plastic box containing desiccant. *** For more information see https://crm.jrc.ec.europa.eu/p/BCR-692 ***

Intended Use:
The CRM can be used for verification of the overall performance of scratch-test instruments, and for establishing control charts for monitoring instrument performance (including stylus) over an extended period. The CRM should not be used to calibrate the scratch tester.
