FAQ - Phospholipide
Wir beantworten Ihre häufig gestellten FragenWho is my contact at Spectral Service AG for phospholipid analyses?
Please send your phospholipid related e-mails to the following e-mail address: phospholipid@spectralservice.de. The responsible study directors in our phospholipid department will answer your request as soon as possible.
If you have questions or requests concerning the financial part of your order (e.g. invoices, bank details, company organization, etc.) or additional analyses, you can also contact our secretary’s office (info@spectralservice.de).
Which phospholipids can be determined within the analysis?
Our routine PL analysis is a multi-component analysis. It covers the quantification of the following phospholipids:
Abbreviation | Phospholipid |
PC | Phosphatidylcholine |
LPC | Lyso-Phosphatidylcholine |
PI | Phosphatidylinositol |
LPI | Lyso-Phosphatidylinositol |
PS-Na | Phosphatidylserine Sodium |
LPS | Lyso-Phosphatidylserine |
SPH | Sphingomyelin |
PE | Phosphatidylethanolamine |
LPE | Lyso-Phosphatidylethanolamine |
APE | N-Acyl-Phosphatidylethanolamine |
PG | Phosphatidylglycerol |
DPG | Diphosphatidylglycerol |
PA | Phosphatidic acid |
LPA | Lyso-Phosphatidic acid |
Other potential but unidentified phospholipids can be detected and are quantified as sum. As a result, we can offer you a total phospholipid content in your sample.
Which matrices are possible for a phospholipid analysis?
We perform the analysis routinely on the following matrices (just to give you some examples):
- Lecithin samples (e.g. soy lecithin, sunflower lecithin, rapeseed lecithin, hydrogenated lecithin, hydrolyzed lecithin, lyso-lecithin, soy beans, etc.)
- Lecithin residues in edible oils
- Capsulated materials
- Marine source (e.g. fish oil, krill oil, fish meal, sea food)
- Egg samples
- Milk samples (e.g. infant nutrition, liquid milk, creams, chocolate, cheese)
- PS enriched samples
- Dispersions, emulsions, liposomal formulations
- Algae samples
- ….
We can perform the phospholipid analysis on nearly every matrix. If you have special samples, that are not listed in the table, please contact us via email (phospholipid@spectralservice.de).
How much sample is required?
Matrix | Approx. sample amount |
Soy/sunflower lecithins (powder or syrup), Krill oil samples, PS samples, egg samples | 5 g |
Milk samples (powder), infant nutrition, fish feed, fish meal | 20 g |
Milk samples (liquid) | 200 mL |
Lecithin Residues in Edible Oils |
20 g |
Capsules/ Gummy bears | 10 pieces |
Liposomal dispersions | 10 g |
If you have special samples, that are not listed, please contact us per email (phospholipid@spectralservice.de).
What is the turnaround time?
The turnaround times are dependent on matrix and daily sample volume at Spectral Service. For most orders, the results will be available within 4-8 working days, but we do not guarantee this. If you need the turnaround time for a specific order, please contact us via email (phospholipid@spectralservice.de).
Is there an urgent service / express fee?
We offer different rush services for a rush fee (+50-200%) in case you need the results faster than our routine turnaround times. We would kindly ask you to contact us in advance, so we can let you know if a faster analysis is possible and for what price.
What are the costs for the phospholipid analysis?
Costs are available upon request. Please contact us via email (phospholipid@spectralservice.de).
How to declare the samples for shipment (from outside the EU)?
If you send us samples of animal origin they are subject to examination by the veterinary authorities at the border control referring to European Commission Decision 2021/632/EC. Please note, the veterinary border inspection causes costs. We will forward these costs to our customer.
- Please declare a value of 1 US$ as samples for analysis have no commercial value.
Sample sending (animal origin):
To ensure a fast process please consider the following information about sample declaration (outside of the package):
It’s important to declare samples on the courier documents in this way, too, to be sure, samples with animal origin will pass the veterinary border station.
Matrix | Declare as | Customs tariff number | Hazard information | Purpose |
Krill oil | Sample of Krill oil | 1504 | Nonhazardous samples | Analytical use only |
Fish oil | Sample of fish oil | 1504 | Nonhazardous samples | Analytical use only |
Fish, shellfish or crustacean samples **) |
Fish samples (captured in the wild) |
1504 |
Nonhazardous samples | Analytical use only |
Fish, shellfish or crustacean samples **) | Fish samples (aquaculture) |
1504 |
Nonhazardous samples | Analytical use only |
Fish feed*) | Sample of fish feed | 2301 | Nonhazardous samples | Analytical use only |
Milk*) | Sample of milk product | 0402 | Nonhazardous samples | Analytical use only |
Egg yolk*) | Sample of egg yolk | 0408 | Nonhazardous samples | Analytical use only |
Attention!
*Fish feed, egg and milk samples require an additional document: a heat treatment certificate about 80°C in the core.
**) Fish, shellfish, or crustacean samples from aquaculture need one of the following documents:
- A health certificate issued by the official veterinarian responsible for the place of origin of the fish/fishery products certifying that the samples of fish, crustaceans or shellfish originate from a third country and that they have been examined by him and found free from transmissible fish diseases specific to that species, or susceptible to that species and whose herds of origin are not subject to animal health restrictions due to diseases affecting fish, crustaceans or Shellfish or are subject to transmissible diseases.
or
A heat treatment certificate about 80°C in the core
A heat treatment must have the following information:
– Please add the AWB/tracking number
– Please sign and stamp the heat treatment
– Declaration: only for analytical use
– The document must declare a heat treatment about 80° C in the core
– Please use an official business paper for the heat treatment document
Sample sending (botanical source):
To ensure a fast process please consider the following information about sample declaration (outside of the package):
Matrix | Declare as | Customs tariff number | Hazard information | Purpose |
Lecithin | Sample of lecithin | 2923200 | Nonhazardous samples | Analytical use only |
Algae | Sample of algae | 12122100 | Nonhazardous samples | Analytical use only |

Are analyses according to GMP also possible for phospholipids?
Yes, it is. If you need some analyses according to GMP, please do not hesitate to contact us (info@spectralservice.de). We will get back to you with all necessary information as soon as possible.
Is your laboratory accredited?
Spectral Service AG is a GMP and GLP certified laboratory, and we are FDA approved. The 31P NMR method (for phospholipid analyses) is developed in our laboratory and has been accepted as the official USP method for krill oil. The phospholipid method is validated for many matrices. Our certificates can be downloaded from our homepage. However, we are not accredited to ISO 17025.
How long does Spectral Service keep the phospholipid samples?
We retain Phospholipid samples 4-5 working weeks after sending out the results, afterwards the samples are disposed of. If you wish, that we should keep the samples longer, please do not hesitate to contact us (phospholipid@spectralservice.de).
