Using a variety of testing methods, we can offer you the following services:
Our High Volume Instrument Testing (HVI) is capable of providing measurement of the following parameters, as well as standalone testing at a reduced fee:

We have a Premier G-Trash Tester that measures the trash content by weight in a cotton sample. This testing method is suitable for merchants and spinners who specify an exact trash content allowance for the shipment in their contract.
We can also measure ‘stickiness' as a separate parameter. This measurement is used to determine level of sugar content and how sticky the cotton is.
Micronaire testing can be conducted on either the HVI or the Sheffield Micronaire Tester. Comparisons between the two instruments show that the results are correlated.
Our Advanced Fibre Instrument System can analyse the physical properties of single fibres and is especially used to determine the nep content.

This includes the identification of genetically modified cotton and the differentiation of cotton species such as Pima / Gossypium Barbadense.
Premier's G-Trash tester provides the overall gravimetrical trash content of a raw cotton sample. A high speed licker-in roller individualises the cotton sample to separate the trash particles from the cotton lint. In order to minimise variation of results, three sub samples of about 10 grams each are prepared from the original sample and tested. The lint is collected separately in a lint box and the trash particles on a tray. The trash particles are then weighed automatically to calculate the trash content in %.
No calibration is necessary. Unlike MDTA (see below), the G-Trash tester does not sort according to trash kind.
G-trash can be used in connection with the Premier ART test to compare the usual optical trash measurement and the trash content by weight on the same sample.

MDTA provides values for the gravimetrical trash content in a sample, unlike High Volume Instrument testing (HVI) where the trash is evaluated by an optical measurement. It separates fibres, general trash and fibre fragments with a particle size of more than 500 microns, as well as dust with a particle size of more than 15 microns from a sample of raw cotton or sliver.
In order to minimise variation of results, two sub samples of about 20 grams each are prepared from the original sample and tested. For evaluation after testing, the different separated fractions are weighed and related to the weight of the testing sample.
MDTA provides important indications for the content of dust and fibre fragments and the cleanability of raw cotton that have influence on the processing of yarn on different spinning machines. Samples for the different separated trash fractions of the tested sample are available on special request.
